A daytrip to the Bassin d'Arcachon is certainly worthwhile if you can withstand the crowds. Depending on which part you want to visit you should count on 65 to 80 miles.
Personally we do not really like crowds and therefore we do not have many pictures to show you from the Bassin d'Arcachon. Below we give you several links to well-known and lesser known attractions. And of course a couple of pictures that we did take.
Should you also think that it's pretty crowded, just keep in mind that by the end of the day you can at least go back to the tranquility of camping La Motte.
The Dune du Pilat just south of the Bassin d'Arcachon is one of the most famous attractions. It is the highest dune in Europe.
You really have to climb the lighthouse Phare du Cap Ferret since the view is fantastic. There is a small museum next to the lighthouse. Did you for example know that 18,000 years ago the coastline was not here but a lot further inland close to Perigueux ?
Le petit train de Belisaire rides from the shore of the Bassin d'Arcachon in Belisaire along the streets to the beach on the other side of the Cap Ferret peninsula. Nice to combine with a visit to the lighthouse a little further.

The island Île aux oiseaux almost in the middle of the Bassin d'Arcachon is well loved by birdwatchers.
The ornithological reserve Réserve Ornithologique near Le Teich on the southside of the Bassin d'Arcachon. Various boat trips are offered here, as is the case almost everywhere around the Bassin d'Arcachon.
Go out on your own to explore the Bassin d'Arcachon near the bird sanctuary almost without making any noise. Something we shall try out ourselves as well.
If you like oysters you should definitely visit the Maison de l'Huitre in Gujan-Mestras which is the village next to Le Teich on the southside of the Bassin d'Arcachon.
The next village, La Hume, used to have a beautiful medieval village in the summer, but unfortunately that has been replaced by some amusement park.
