As its name suggests, this is the largest beach in Préfailles. Lively and supervised in the summer.

Such a beautiful day. A very cool route. A bit lacking in signs. As for directions. But it's okay.

Not a very difficult circuit with beautiful passages on the Gatineaux and Gros Caillou ponds. The starting point can be from the charming port of St Michel chef chef

If you finish your bike ride at the end of the D 313, you will arrive at the end of Pointe Saint-Gildas. After getting your fill of adrenaline in the saddle, admiring the ocean as far as the eye can see is a sublime experience.

This charming fishery on Tharon Beach stands out from other fisheries thanks to its bright color.

Unfortunately we didn't see it when we arrived (30.8.24) in the rain. The next day, when it was humid and dry, we were able to marvel at this enormous animal.
