Nature Festival in Plaisir 2026, the lineup of free activities in Yvelines

The 22 and 23 May 2026, the town of Plaisir, in the Yvelines (78), teams up with the Fête de la Nature to offer a program of free activities focused on discovering local biodiversity. Guided walks, an introduction to wildlife photography, a deep dive into the life of a beehive… all set in the heart of the parc du château de Plaisir and the Sainte-Apolline forest, just a stone's throw from Saint-Quentin-en-Yvelines.

The city isn’t new to the topic: branded as a Nature-Friendly Territory, it carries out biodiversity initiatives year-round, and the Nature Festival is the occasion to share them with the public. This 2026 edition also marks the 20th anniversary of the event in France, held every year since 2007 by the Nature Festival Association.

Note also, from May 18 to 24, a roving photo exhibition titled "A Thousand and One Looks" rolls out across the city. It spotlights Plaisir-based photographers and their view of the local nature—a tasty preview ahead of the weekend’s activities.

The program works for both families with kids and nature-loving adults.
