Hiking

Exploring the marshes of Île d'Olonne will reveal a unique ecosystem teeming with life. This vast wetland, home to a variety of flora and fauna, offers a peaceful retreat from the hustle and bustle of coastal towns. You can hike along winding trails, spot colorful birdlife, and marvel at the beautiful sunsets over the marshes. Don't forget to visit the charming port of Les Sables-d'Olonne, known for its maritime heritage and lively atmosphere.

Mountain biking

Rather than going around the marshes, why not take a walk right in the middle.
