On Wednesday, September 24, 2025, the Tous en Forêt event returns for a 5th edition in the Île-de-France region. A day to meet ONF foresters and find out more about the challenges of forest management, at over 40 participating forests in the region.
Climate change, forest management, biodiversity protection, timber harvesting... There are many questions about the future of forests and their preservation. To answer these questions, the foresters of theOffice National des Forêts are mobilizing through the Tous en Forêt event, which returns for a 5th edition in Ile-de-France, on Wednesday September 24, 2025.
They invite you to come and talk to them during this initiative, which takes place in the state, municipal and regional forests of the Paris region. It's a unique opportunity to put your questions directly to those who are working to preserve our natural spaces, and understand the challenges of tomorrow.
The program in the Île-de-France region is particularly rich, with rendezvous points spread throughout the state-owned and regional forests. Each meeting point offers a guided tour with explanations suitable for all ages.
Please note that most events are unreservedly bookable, with the exception of certain visits to the forests of Seine-et-Marne. To register, simply click on the links below!
