Stand on the Faidherbe Bridge in the late afternoon and the city arranges itself in front of you: the grid of the island, the painted balconies, the river sliding north toward the sea. Cross to the mainland and the light changes again, and you understand why so much of Saint-Louis is best seen on foot.
Saint-Louis suits travellers who like walking, colonial architecture, fishing harbours and birdlife more than they like resorts. It rewards slow days: a museum in the morning, a beach in the afternoon, a long dinner on the island. This guide covers the sights and experiences worth your time, plus a plan for a single day.
Top things to do in Saint-Louis
1. Faidherbe Bridge
The bridge connecting Saint-Louis island to the mainland is the natural starting point for any visit. A bridge opened here in 1865, named after the colonial administrator Louis Faidherbe, and the current, larger one opened in 1897 and inherited the name. There is a myth that Gustave Eiffel designed it; his company in fact came second in the bidding process.
Walk it rather than drive it, and use it to orient yourself: the island lies on one side, the mainland on the other. The Syndicat d’Initiative sits in the Governance building opposite the bridge, so cross here first and pick up the urban walk they have mapped out.
2. Guet N’Dar
Walk to Guet Ndar, the fishing village on the Langue de Barbarie, and watch the fishermen bring in their catch. Dozens of trucks wait to buy up the fish and carry it into the interior, and local people carry the catch in baskets on their heads and necks. Nearby, colourful pirogues are always under construction, so you can see nearly every stage from the first carvings to the final painting.
Women smoke and dry fish next to the beach in vast cauldrons, and there is a decent-sized market here, smaller than the Sor market two bridges away. Be aware that the residential district is extremely crowded, and the beach shows the effects of overcrowding in its sanitary conditions and insufficient trash disposal. If you are lucky you might get a good deal on seafood.
3. Saint Louis Cathedral
This Roman Catholic church is the oldest functioning church in West Africa, opened in 1828, and serves as the seat of the Diocese of Saint-Louis du Sénégal. It is notable that Saint-Louis had no real church before this, despite almost two centuries of European presence here.
Pair it with a walk through the surrounding streets of the island, where many buildings keep their old character, with brightly coloured facades and balconies. The island was named a UNESCO World Heritage site in 2000.
4. Musée de l’Aéropostale Jean Mermoz
This museum covers the colonial airmail service that played a role in the development of Saint-Louis, and includes an exhibit about the pilot Jean Mermoz. It is open Monday through Saturday, and the entrance fee is 2000 CFA.
It is a compact stop, so combine it with the rest of your island walk rather than making a separate trip. You can reach the museum at +221 33 961 24 55 or sltourisme@orange.sn.
5. Grand Mosque of Saint-Louis
The Grande Mosquée de Saint-Louis is a beautiful but rather low-key mosque in colonial-style architecture. Its two minarets each feature both a clock and a ringing bell.
It fits easily into a walk across the island, so see it on the same outing as Saint Louis Cathedral and the colonial streets nearby.
6. Plage Hydrobase
The long Plage Hydrobase stretches along the Langue de Barbarie Peninsula and is the proper beach of Saint-Louis, popular with locals, tourists and cattle. A number of the city’s hotels are along or near this beach.
It sits past the fisherman cemetery on the Guet N’Dar side, which makes it a good end point for a walk down the peninsula. Note that you will find plastic and other waste in the sand.
7. Plage de Sal Sal
Plage de Sal Sal, to the north of the city, is pristine and deserted, so much so that you might not encounter anyone else there. The beach stretches across the border to Mauritania, so be careful not to go too far north.
There is a chance you will see police officers on your way here; tell them that you are going to the beach.
8. Institut Français
This French cultural centre on Avenue Jean Mermoz has a café, a library, and often concerts, films and art exhibitions. It is open Monday to Friday 08:30–12:30 and 15:00–18:00, and Saturday 08:30–16:00.
Pick up the monthly program brochure at the centre, at one of the hotels around Saint-Louis, or at the Syndicat d’Initiative, so you can time your visit to an event. You can also reach it at +221 33 938 26 26 or direction@ifsaintlouis.org.
9. Office de Tourisme / Syndicat d’Initiative
The local tourist office on Rue Milles Lacroix is the place to start if you want the city’s mapped-out urban walk, which takes you around the island’s colonial architecture. It also offers a smaller selection of tours.
It sits in the Governance building opposite the bridge, so it is easy to visit on your way onto the island. Contact it at +221 33 961 2455 or sltourisme@orange.sn.
10. Guided tours with Sahel Decouverte and Saint Louis Jeunesse Voyages
These are the two main tour operators offering tours in and around the Saint-Louis area and northern Senegal. Daily tours include a tour of the island, the Parc National des Oiseaux du Djoudj, the Parc National de Langue de Barbarie, and a boat ride along the Senegal River to see mangrove trees. Longer trips are available if you have more time.
Contact the agencies for their current offerings, since these change. Sahel Decouverte – Agence de Voyages can be reached at +221 33 961 5689.
11. Langue de Barbarie Peninsula
The peninsula holds the fishing village of Guet N’Dar, the bustling fish market, and glimpses of the colourful pirogues used for fishing. Further down, past the fisherman cemetery, is the Hydrobase, a good place to spend a day at the beach.
At the very south end of the peninsula lies part of Langue de Barbarie National Park, which is home to a variety of bird species. Walking the length of the peninsula covers several of the stops above in one outing.
12. Ndar-Toute-plage
This is where the city meets the Atlantic, and you can see the colourful fishing boats here. It is worth a look for the boats rather than the beach itself.
The beach unfortunately also doubles as a kind of landfill, so it is not a place for beach activities like tanning or swimming. Combine it with a walk along the waterfront rather than planning a beach day around it.
13. Saint-Louis International Jazz Festival
This annual event generally occurs in late May for about a week, and is the most important jazz festival in Africa. The 2025 edition attracted over 30 jazz musicians, along with visitors from around the world.
The events take place all over town rather than at a single venue. Dates and programs can be found online, so check them before you book travel if the festival is your reason for coming.
14. Les Fanals
Held each year between Christmas and New Year, Les Fanals is a night parade of lanterns lit from within by candlelight, resembling carnival floats and accompanied by songs and drums. This historic procession is unique to Saint-Louis and was initiated by the signares, who in colonial times were the colonists’ prestigious wives.
Because it falls in the holiday period, plan your accommodation well ahead if you want to be in the city for it.
If you only have one day
Morning. Start at the Office de Tourisme / Syndicat d’Initiative in the Governance building opposite the Faidherbe Bridge and pick up the urban walk. Cross the Faidherbe Bridge onto the island and follow the walk through the colonial streets, stopping at Saint Louis Cathedral and the Grand Mosque of Saint-Louis. If you have time before lunch, add the Musée de l’Aéropostale Jean Mermoz, which is open Monday through Saturday.
Afternoon. Head to the Langue de Barbarie Peninsula and walk to Guet N’Dar to watch the fishermen bring in their catch and see the pirogues under construction. Continue past the fisherman cemetery to Plage Hydrobase for the rest of the afternoon on the beach.
Evening. Return to the island and check the monthly program at the Institut Français for a concert, film or exhibition, or simply have dinner on the island. If you are visiting between Christmas and New Year, Les Fanals may be running; if you are visiting in late May, check the dates of the Saint-Louis International Jazz Festival.
