Andernos is a seaside town on the north-east shore of the Arcachon basin, with a long sand beach and oyster farms around the bay. It suits families wanting basin water rather than ocean waves. The basin is tidal, so swimming depends on the time of day.
Andernos-les-Bains lies on the north-east shore of the Arcachon basin and has a sand beach about 5.4 km long. The basin is tidal: it covers around 150 square kilometres at high tide and drops to about 40 at low tide, leaving mud and sand bars. That changes the character of a beach day, because water comes and goes. Most homes here have a private pool, and they sleep from two up to large groups, so swimming does not depend on the tide. Homes sit close to the town rather than scattered around the shore.
The neighbouring town to the north-west of Andernos, also on the shore of the bay.
The Isle of the Birds sits almost in the middle of the basin.
The lighthouse stands at the tip of the bay, where a narrow channel called Les Passes joins it to the sea.
A very large dune just south of the bay's entrance, described as the longest in Europe.
Bordeaux-Mérignac is the closest airport to Andernos, about 30 km away. You will want a car, both for the basin villages and for trips to the dune and the lighthouse at Cap Ferret.
Yes. The commune has a sand beach about 5.4 km long. The basin is tidal, though, so at low tide much of the water retreats and leaves sandbanks, which means timing matters for swimming. The bay can change dramatically within a single day.
Yes, along with the rest of the bay. Andernos has its own oyster farms and small fisheries, and the bay as a whole is well known for oyster cultivation, with farms visible all around its shores.
Not directly. Andernos is on the sheltered north-east shore of Arcachon Bay, and a narrow channel about 3 km long called Les Passes joins the bay to the open sea at its south-west corner.
Bordeaux-Mérignac, about 30 km away, is the closest airport to Andernos. From there a hire car is the simplest way to reach the basin, since the shore villages are spread around the bay.
