Mauritania to Senegal Border Crossing Guide (Overland Travel) — Step-by-Step - Lost In A 4x4

Mauritania to Senegal Border Crossing Guide (Overland Travel) — Step-by-Step

Lost in a 4x4 Overland Guide Border Crossings with a Vehicle May 2026

The border crossing from Mauritania to Senegal is painless and easy—far less complicated than the nonsense crossing from Morocco into Mauritania from Morocco into Mauritania. We chose to cross at Diama, a smaller and far more organized border than Rosso. Diama has lighter traffic, fewer crowds, and none of Rosso’s long-standing corruption reputation.

This is a step-by-step guide for overlanders driving from Mauritania to Senegal, based on our own experience. You’ll learn everything you need to know about crossing with a vehicle and how to extend your passavant. Follow along with the maps to get familiar with each step—so you can confidently decline hiring a fixer!

Do you need a visa?

As American citizens, we did not need a visa. The same applies to most European passport holders.

Carnet de Passages en Douane (CPD)

We initially entered Senegal without a Carnet de Passages en Douane (CPD) and had no issues at all. The border process was straightforward and inexpensive.

Later in our journey, we obtained a CPD, and in this guide we also explain how the Carnet works, how to use it at border, and the steps to extend or manage it during long-term overland travel. Full details and costs are explained below.

Mauritania to Senegal Border (Diama Crossing) – Approach from Nouakchott via Parc National du Diawling

Most overlanders approach Diama from Nouakchott, as we did. Take the N2 the coast toward Rosso, then turn right at the final split toward Keur-Macene. About halfway through town, take the right-hand dirt road toward Parc National du Diawling—this is the last road you’ll drive in Mauritania.

The track crosses the national park and can be bumpy, but there are usually two parallel roads, so you can switch depending on conditions. It’s easily doable in 2WD during the dry season. The drive is nice: birds everywhere, warthogs crossing the road, and—if you’re a good spotter like Brett—even crocodiles (we saw one).

At the end of the park, you’ll reach a small “toll booth.” Pay the park entrance fee of 200 MRU per person and keep the receipt.

Where to Stay Before the Border

We strongly recommend staying near the border the night before so you can arrive as soon as it opens. This avoids crowds, keeps the process smooth, and reduces any risk of corruption.

We stayed at the government camp just past the park toll booth. Drive about 400 meters, turn right, and the camp is a short distance down the road. It’s where national park staff stay.

  • Cost: 500 MRU
  • Secure, with a restaurant and clean toilets

Some travelers wild camp along the road, but we were told camping inside the park is not allowed, and you may be asked to move. Do your own research if you choose that option.

Exiting Mauritania

We arrived before opening and parked right at the gate. The border opens at 8:00 am. The guard was friendly and made sure we entered first, even with locals trying to cut the line.

Before driving in, a guard will ask for “La Fiche” (Download La Fiche (French + English PDF) here). After that, park your vehicle.

Customs (Douane)


Walk to the customs building on the right of the old blue police building (second building from the entrance). Go to the office on the left marked “Chef de Poste.”

Hand over your passavant (or Carnet, if you have one) and passport. An officer will cancel the passavant (or the Carnet) and take photos of the front and back of your vehicle.

Police

Head to the last building on the left before the exit. Find a uniformed officer outside and give him your passport, visa (if applicable), and carte grise (vehicle registration). He’ll ask you to show him your vehicle from the outside, then walk you inside the police office.

At the crowded window on the left, he’ll pass your documents to the officer inside. This area is usually packed with people trying to reach the window, and locals will be pushing in—stay calm and patiently work your way forward. You’ll likely be sharing the window space with others sticking their heads in, so just point out which documents are yours. You’ll be asked a few basic questions in French, your passport will be stamped, and you’ll receive a small white paper with a stamp.

Exit


Hand that paper to the guard at the exit gate—and you’re done! 

We paid nothing to exit Mauritania. The officers were polite, the process was efficient, and aside from squeezing into the police window, everything went smoothly.

Money Exchange (Important)

Before leaving the Mauritanian border post, exchange any remaining Ouguiya (MRU) into CFA The Mauritanian Ouguiya (MRU) is a restricted currency, which basically means you’re not really supposed to bring it into the country or take it out. If that doesn’t fully cover the passavant, bridge toll, and parking, exchange Euros or USD into CFA as well—you’ll need CFA on the Senegalese side.


Quick tip: keep enough Euros to pay for insurance and, if applicable, the no-CDP fee. Credit cards are not accepted.

No Man’s Land

Mauritania and Senegal are separated by a dam. Cross it and, immediately on the Senegalese side, an officer will collect the official fee of 4,000 CFA. You’ll receive a receipt.

Entering Senegal

Continue to the police station (second building on the right). Park in the small lot. At one of the two windows, hand over your passport, international driving permit, driver’s license, and carte grise.

The officer will enter your details, ask a few basic questions (some English is spoken), stamp your passport, and take biometrics (photo + fingerprints). The process is quick, professional, and free.

Next, drive across the street to Douane (customs) and park. At the window, hand over your passport and carte grise.

Customs Scenarios

A) If you have a Carnet de Passage


Present it here. The process is fast. Pay 5,000 CFA (official fee). You’ll receive 48 hours, which must be extended in Dakar (extension: 3 months-details below).

B) If you do NOT have a Carnet and your vehicle is older than 8 years

You’ll pay €250 and typically receive around 10 days (duration may vary). Extensions are possible in Dakar, but costs are unclear (travelers we met did not extend).

C) If your vehicle (including motorcycles) is newer than 8 years and you do NOT have a Carnet

Tell the officer your vehicle is newer and request a passavant. I was asked about a Carnet a few times; a quick visual check of the vehicle was enough to confirm eligibility.
Submit your passport, international driving permit, and carte grise.

  • Fee: 5,000 CFA (official)
  • Validity: 48 hours, extendable in Dakar (details below)

Before leaving the parking lot, a customs officer will inspect your vehicle. In our experience, it was very quick — he only asked us to open a few compartments in the back. The officer was friendly and had a great sense of humor.

Vehicle insurance (Carte Brune)

Once you receive your passavant, head to the small restaurant behind the Douane building (or park in front). Before exiting the border area, pay 1,000 CFA for parking and keep the receipt.

At the restaurant, ask the nice lady in the kitchen for “Carte Brune.” Often, a well-dressed agent will approach you at customs and walk you over. He’ll collect your vehicle details, submit them digitally (using his phone), and have the policy printed and delivered.
Double-check all details before paying.

  • We paid €30 for 30 days of insurance for our Jeep Wrangler Rubicon.

Total time from exiting Mauritania to insurance in Senegal: 2 hours. Everything was smooth, professional, and corruption-free.

A traveler using a fixer finished about 10 minutes earlier than we did.

Getting insurance at the border is expensive. We chose to extend our Carte Brune for six months so we wouldn’t have to repeat the process at every ECOWAS border. We arranged a new policy in Dakar at the AXA insurance office located at the bottom of the Douane building (full details below—see “Extending Your Vehicle’s Passavant”). The cost was $69 USDs for six months, making it significantly cheaper than buying insurance at the border.

The insurance coverage for The Gambia comes as a separate voucher, which is stapled to the main insurance form. Make sure to tell your insurance agent that you need Gambia coverage, so they don’t forget to include this voucher with your policy.

Before deciding to skip insurance at Diama, there’s one important thing to keep in mind: third-party insurance is mandatory. There are police checkpoints almost immediately after the border on the road to Saint-Louis and along the route to Dakar. That said, some overlanders choose to get their insurance in Dakar and report no issues. In our case, we were not stopped at any police checkpoints between the border and Dakar. We were stopped later by police and Douane officers in towns in the southeast near The Gambia, and none of them asked for proof of insurance.

What Is the Carte Brune?

The Carte Brune is third-party vehicle liability insurance valid across multiple ECOWAS / West African countries. It’s mandatory in Senegal and popular with overlanders because it simplifies future border crossings—one policy, multiple countries.

Police Checkpoints

We encountered several checkpoints—both police and Douane—on highways and in cities. We were stopped a total of four times, three in the southeast region near The Gambia and once near Kaolac.

We did experience one corrupt incident. On our way to Kaolack to the Douane officer to switch our passavant to a Carnet de Passages, we were stopped at a police checkpoint. As soon as we handed over our passavant, the officer walked back to his commander and then motioned for us to come over.

When I approached, the commander told me we had a fine. Surprised, I asked why. He claimed we had crossed the center line in a no-passing zone. I immediately denied it. I explained that we are careful drivers and that in the United States crossing a solid line carries a significant fine, so we would never knowingly do that. He then commented that Brett was a terrible driver, which I firmly rejected.

Brett joined the conversation after I told him we were being fined. Calmly but confidently, he explained that if we had crossed the line, it was only because another officer had waved us to pass the vehicle in front of us—then immediately signaled for us to pull over.

The officer insisted on the fine, but we politely said that was fine—we would wait there as long as necessary. I then mentioned that we had an appointment with Patrick, the Douane officer in Kaolack, who was expecting us. The commander asked when we were due to meet him, and we replied, “Very soon.” I added that we would have to inform him we were delayed because of this stop.

At that point, the commander spoke quietly with the officer who had pulled us over. A few minutes later, our passavant was handed back to us without further discussion. We walked away and continued on our way.

At all other police checkpoints, the officer checked our passavant and international driving permit, matched the license plate, and waved us through without issue.

The Douane checkpoint was slightly more involved. After reviewing our vehicle’s passavant, and the international driving permit, we were asked to pull over and step into a small roadside Douane office. One officer asked for a Carnet de Passage. I calmly explained that our passavant was valid and sufficient due to the age of our vehicle. He then claimed the passavant was expired. I disagreed, and he flipped it over, read the stamp indicating “15 jours,” handed the document back, and let us go.

The interaction remained polite and cordial throughout.

In Dakar, checkpoints consistently waved us through. Outside towns, buses, minibuses, and trucks usually stop; private vehicles are stopped occasionally. We were also waived though the military checkpoint near Niokolo-Koba National Park.

How to Handle Fines & Corruption

Our strategy: be prepared.

  • Keep all documents organized and ready
  • Ensure your vehicle is legal and compliant
  • Know basic local traffic rules
  • Carry required items (fire extinguisher, triangles, etc.) within easy reach

Some officers look for excuses to justify unofficial fines. Stay calm, respectful, and patient. Hand over only what is requested (documents—nothing extra). Say less; silence often helps. If you don’t speak French, don’t try—the language barrier can work in your favor.

If they point out something like window tint, explain it’s factory-installed and, if needed, show purchase photos (this happened to a French overlander we met).

Most importantly: refuse corruption at all cost, paying unoficial fines directly harms the travelers who come after you!

Over the years, we’ve encountered plenty of corrupt officers who invent rules in an attempt to collect an on-the-spot “fine”, We’ve never paid one. When something doesn’t feel right, we stay calm, ask for the official regulation that justifies the fine, and are fully prepared to wait it out, they eventually get tired and let us go.

That said, if a fine is legitimate, we pay it without issue. For example, in Morocco we were fined for speeding—the officer had a radar and asked us to pay on the spot. We quickly confirmed online that in Morocco, fines below a certain amount are legally paid immediately. We asked for an official ticket, the officer issued one, and we paid the fine happily.

Mandatory Vehicle Equipment in Senegal

When driving in Senegal, especially if you’ll be stopped at checkpoints or police controls, make sure your vehicle carries the following items:

1. Two Warning Triangles

You must have at least two reflective warning triangles in your vehicle to place in front of and behind your vehicle in case of a breakdown or accident.

2. High-Visibility Vest (Gilet)

At least one high-visibility safety vest must be inside the passenger compartment (not tucked away in the trunk), so you can wear it if you exit the vehicle roadside.

3. Fire Extinguisher

Two functional fire extinguishers (not expired) are required in the vehicle and should be accessible in case of emergency.

4. First-Aid Kit

A basic first-aid kit is required in-car for emergencies (band-aids, gauze, antiseptic, etc.).

Extending Your Vehicle’s Passavant

If you’re like us and entered Senegal with a 48-hour passavant, you’ll probably find yourself hustling to Dakar to get an extension.

The Douane office is on the 4th floor of the AXA insurance building, right across from Place de l’Indépendance. On Google Maps, search:
“Place de l’Indépendance Immeuble AXA Assurance.”

It’s right in the middle of downtown Dakar, so do yourself a favor and go early in the morning—traffic gets wild fast.

Parking

You can park around Place de l’Indépendance (the park). There are uniformed guys who’ll guide you into an open spot and keep an eye on your vehicle. We paid 1,000 CFA, and everyone was happy.

If You Have a Passavant

Go in through the entrance on the right side of the AXA insurance office (coordinates 14.669129047503093, -17.43158857540336) “Residence Cap vert” and head up to the 4th floor. You can either take the vintage elevator or get a workout on the stairs.

Once upstairs, the office on the right has a sign on the wall “Direction Regionale Dakar-Port”. The office straight ahead (slightly to the left) is where you actually get the extension, there is a sign on the door “Passavant de Circulation”.

The agent will most likely be sitting at his desk on his phone. Make sure you clearly let him know you need help—standing quietly in the doorway will get you absolutely nowhere.

You’ll get:

  • A 15-day extension
  • A new stamped slip stapled to your passavant
  • Cost: 5,000 CFA

The area is actually pretty nice, so once you’re done, it’s a good excuse to wander around downtown Dakar while you’ve got a decent parking spot.

Second Extension (and That’s It)

You can get one more 15-day extension at other Douane offices, including Dakar, Saint-Louis, Tambacounda, Kaolack, and Ziguinchor.

We decided to get our second passavant extension in Kaolack, and it was fast and easy. The Douane building is located at (coordinates 14.133812089694475, -16.077386319906203). Once inside, walk through the small hallway to the right — the office is immediately on your right-hand side. The customs agent, Patrick, is very professional and friendly. He will stamp your passavant and collect the official fee of 5,000 CFA.

Note that only two 15-day extensions are allowed — no further extensions are possible.

When I received my passavant extension, a new customs building was still being completed. It’s possible that by the time you go, the office will have moved to the new building. The new location is just one block away, in the direction of the Chambre de commerce / Port de commerce. If you’re standing in front of the current douane building facing it, the new customs building is one block to your right.

If You Have a Carnet de Passagges en Douane

If you are a Carnet de Passages holder, you will still need to obtain an extension after the first 48 hours. The good news? This process is much easier—you won’t have to deal with downtown Dakar. Instead, head directly to the Douane offices near the port.

The office is called Bureau Guichet Unique des Véhicules (coordinates 14.695507835386385, -17.43660355582092).

Get there before they open so you can grab a good parking spot. We parked on the dirt area next to the street, along the side of the building (across from a car dealership). The guards told us to park there so we wouldn’t get boxed in and could keep an eye on the vehicle.

The building is newer and nice—clean toilets in the back, friendly guards, and professional agents. The process is quick and straightforward.

You’ll need:

  • Your Carnet de Passages
  • A copy of the vehicle registration (carte grise)
  • A copy of your passport

First, go up to the second floor. The office you need is the second door on the right—if it’s closed, just knock. Hand over your documents, and the officer will record your Carnet de Passages details into their official ledger. He will then stamp the Carnet and remove the full importation voucher.

After that, head back downstairs. As you enter the building and walk past the first waiting area, you’ll see a second small waiting area with a table offering coffee, tea, and small snacks. Facing forward, the correct office is the door straight ahead on the left. The officer there will stamp and sign the counterfoil to complete the process.

The cost is around 5,000 CFA, and whatever they charge will be the official rate. We actually went here by mistake at first, and the agent kindly explained that this office is only for Carnet holders.

Navigating Vehicle Documents in Senegal: Passavant vs. Carnet de Passages

Just in case you ever find yourself in a similar situation, here’s our experience crossing into Senegal with a vehicle. While most travelers won’t encounter this issue, it’s worth sharing.

We entered Senegal using a passavant. About 10 days into our trip, we realized we needed a Carnet de Passages to continue traveling in Senegal after a 19 days pause in our journey due to a family emergency. Our passavant was nearing its expiration, so to legally stay and move around Senegal, switching to a Carnet de Passages became necessary.

We first went to Kaolack, where I had received my last passavant extension. There, we were informed that they weren’t able to cancel the passavant and use the Carnet instead. We were also told we couldn’t leave Senegal to enter Gambia with our passavant and later re-enter Senegal using the Carnet. The office even called Dakar to confirm the rules.

The solution: we had to go to Dakar before the passavant expired and get the importation voucher stamped at the Bureau Guichet Unique des Véhicules. The process in Dakar was quick and straightforward. Both officers we dealt with were professional and friendly, and we didn’t have to pay any fees.

After the process, our vehicle was officially under the Carnet de Passages, allowing us to stay in Senegal without worrying about passavant limits. The officer mentioned that we could remain for up to one year, though we only needed a few more weeks before continuing our journey south.

Going to The Gambia and Back into Senegal

If you plan to dip into The Gambia and return to Senegal:

  • If your passavant is still valid, just show it at the border when you come back—no new paperwork.
  • If you’re traveling with a Carnet de passages, you’ll get a new stamp when you re-enter Senegal, and this time there’s no 48-hour limit.
