The initiative Oh my bloc!

Oh My Bloc is a bouldering festival aiming to inform and educate climbers who are as passionate as we are about climbing in an environmentally-friendly way. We’re delighted that the passion for bouldering is contagious, and in a magical forest, we have to adapt our gym routines to a shared and fragile natural environment.

festival

There will be rock climbing in a natural environment, of course, with adult and children’s competitions and introductory courses. There will also be a magnificent final on our newly-covered bouldering wall. And there will be round tables (environment and climbing, training versus well-being, safety in the forest), documentary resources, a photo exhibition, an exhibitors’ village, hold carving, a nature tour, a forest reading… and above all plenty to eat, drink and party about.

Bouldering

You can climb on the Haute Pierre site with its 150 boulders (access by shuttle), on the new Milly-la-Forêt climbing wall, due to be completed in spring 2025, and on the FFME climbing wall.

Come and improve your skills on the 7 Oh My Bloc structures! New challenge/training area in the village.

Join the local climbing club: Club du Lucane Agile de Coquibus, for young to strong climbers.

Take action

The more visitors there are on natural sites, the more impacts there are, such as abandoned garbage, uncleaned chalk and soil erosion caused by trampling.

Workshops will enable you to build steps, maintain the soil, pick up garbage or clean boulders. It's the perfect way to bring the forest back to life in the face of all these climbing enthusiasts.

Discover

If you're unfamiliar with the sport, there will be introductory courses in the forest on Saturday morning and Sunday afternoon. You'll also be able to discover the climbing and hiking areas near Milly-la-Forêt.

If you're a more experienced climber, you'll be able to deepen your knowledge of climbing, with workshops on how to make holds, or of the environment, with the discovery of the habitats, fauna and flora of the Haute Pierre.

Cité escalade

Milly-la-forêt offers a climbing territory that extends from east to west with magnificent rocky chaos. This world-famous site is full of resources for your climbing.

Take the opportunity to discover the region's natural, craft and cultural treasures: the Maison du Parc Régional du Gâtinais, the Conservatoire des Plantes Médicinales Aromatiques et à Parfums, Cyclop, the Maison Coteau, the Chapelle des Simples and many more.

If you’d like to join the adventure, you can volunteer for the festival, set up a stand in the village, contribute to the prizes for the competitors, and also sponsor the festival and the Oh My Bloc initiative and become part of a sustainable approach to nature sports.
