Saint-Gilles-les-Bains: Réunion's Beach Town & Coastal Base
Plan your trip
Réunion’s coastline is largely inhospitable for swimming — the east coast is exposed to the Indian Ocean swell, the south is volcanic cliff, and the north is turbulent near Saint-Denis. The exception is the west coast between Saint-Paul and Saint-Pierre, where a fringing coral reef creates a protected lagoon system. Saint-Gilles-les-Bains sits at the center of this lagoon: the town has a marina, a beach, the island’s most developed tourist infrastructure, and the best access to the underwater world of the barrier reef.
It is the most conventional “beach destination” part of Réunion — which, in the context of a volcanic island primarily known for mountains and hiking, means there is actually a beach.
The Beaches
L’Hermitage Beach
The longest beach in the lagoon — a 3 km stretch of white sand (actually ground coral) behind the reef. The sea inside the reef is calm and shallow (1–3 meters) making it genuinely swimmable. Sunbeds available from beach operators; free public sections throughout.
The beach is backed by a shading row of filao trees (casuarina) — the classic Réunionnaise beach setup. Weekends bring the entire local population; weekdays are quieter.
Shark advisory: The west coast lagoon has had bull shark incidents since 2011 — the APNÉE de la Réunion association monitors conditions, and swimming is occasionally restricted. The reef crest and open ocean beyond it are designated no-swim zones; within the lagoon, the risk is managed. Check the daily bulletin (posted at beach entrances and at www.info-requin.re) before swimming.
Les Roches Noires Beach
North of L’Hermitage — a volcanic sand beach with black sand, smaller and less frequented. The visual contrast between the black sand and turquoise lagoon is striking.
Saint-Paul Beach
North of Saint-Gilles, a large beach fronted by a weekly market (Thursday and Friday mornings) — the Marché de Saint-Paul is one of the best markets on the island, combining food, spices, local crafts, and vanilla.
Diving and Snorkeling
The reef off Saint-Gilles is one of the best diving sites in the Indian Ocean — live coral gardens, drop-offs, turtle sightings, and a diversity of reef fish. Several professional dive centers operate from the marina:
Blue Marine Plongée, Padi Center Réunion, and several others offer guided dives from €45–65 per dive including equipment. Discovery dives for non-certified swimmers available from €55.
Snorkeling: The lagoon reef is accessible directly from L’Hermitage beach — the inner edge of the reef is 200–300 meters from shore. Bring or rent a mask and fins; the snorkeling is good enough that many visitors don’t need to dive. Reef organizations in Saint-Gilles rent equipment and provide maps of the best snorkel spots.
The Marina and Town
The marina at Saint-Gilles has the feel of a scaled-down Côte d’Azur fishing port — restaurants along the quai, boat charter operations, and the pleasure craft that come and go. The town behind the marina has a distinctly French Caribbean feel: a combination of Creole buildings and modern French-colonial architecture.
Sunset strip: The restaurant strip along the waterfront is the most animated part of the town, particularly on Friday and Saturday evenings. Seafood, carry (Réunion curry), and standard French bistro fare.
Day Trips from Saint-Gilles
Piton Maïdo (2,205 m): The viewpoint above the cirque de Mafate — one of the most dramatic panoramic views in Réunion, with the car-free cirque visible below and the ocean beyond. 45 minutes from Saint-Gilles by car. The road is narrow but paved.
Saint-Paul town: 10 minutes north — the historic town of Saint-Paul has a famous cemetery (the grave of the pirate La Buse and assorted 18th-century figures), a colonial-era architecture streetscape, and the Thursday/Friday market.
Cascade Niagara: A waterfall inland from Saint-Paul — accessible via a short hike from the road. Less dramatic than the cirque waterfalls but easily combined with a Saint-Paul day trip.
Practical Notes
Getting there: Saint-Gilles is 50 km south of Saint-Denis on the RN1 — about 1 hour by car (longer in rush hour). Car rental essential (see Réunion Practical Guide).
Accommodation: The largest concentration of hotels on the island is in and around Saint-Gilles. Options from budget guesthouses (€60–80) to the major resort hotels (€150–350). Book directly; the French holiday market means peak periods (July–August, December–January) sell out well in advance.
Climate: The west coast is the driest part of Réunion — typically sunny when the cirques are under cloud. The rain shadow effect makes this side significantly drier than the east coast.
