The Lausanne area boasts the biggest sandy beach around. Due to limited parking, it's advisable to consider biking as a means of transportation if possible. The water near the shore is relatively shallow. A promenade stretches along the entire length of the beach, accompanied by amenities such as a restaurant, restrooms, and a small buvette offering refreshing drinks, snacks, and paninis.
The local beach is a favorite spot for our family, where our children and grandchildren used to swim. Now, the adults enjoy activities like swimming, paddle boarding, and parasailing.
The place is absolutely stunning, but it tends to get quite crowded. My suggestion would be to walk a bit further along the shore, where you'll find a park that offers an equally delightful experience for swimming and sunbathing on the grass.
