Sète and the Thau lagoon by boat: canals, oysters and Mont Saint-Clair

Renting a boat in Sète: the 'Venice of Languedoc', the Thau oyster farms, the corniche and Lido beaches — a double playground, sea and lagoon.

By Clément Lacaille, editor of Boat-Comparator · updated 7 Aug 2026

Sète offers a rare privilege: two cruises in one. Seaward, the Mont Saint-Clair corniche and twelve kilometres of beaches; landward, the Thau lagoon, an inland sea carpeted with oyster tables where you weave between the farms.

Seaside: the corniche and the Lido

From the old port, pass beneath Mont Saint-Clair: the corniche, the La Nau coves, then the immense Lido beach running to Marseillan — anchor on sand off a beach that never ends. In summer the thermal breeze fills in at noon: morning rules.

Lagoon side: Thau and the oysters

Through the canal you switch to Thau: flat water, oyster tables aligned like vineyards, and the villages of Bouzigues and Mèze where lunch is the pontoon's own harvest. Buoyed channels are mandatory — the tables are real obstacles — and speed drops near the farms.

The Sète canals

Crossing Sète by its canals between coloured quays is a moment — at walking pace, giving way to the professionals: fishing works here. Check the opening hours of the mobile bridges for clearance.

Budget and boats

Perfect license-free waters (flat lagoon, short distances): €80-160 per day. RIBs and motorboats €180-400 to combine sea and lagoon. Sète, Marseillan and Mèze line up offers on the same lagoon — the compared search is a must.
