What Travellers Say
Reviews Summary
Isatis is highly praised as a top bouldering spot in Fontainebleau, lauded for its rewarding routes, beautiful natural setting, and variety of problems for all skill levels. While grades can be subjective, the overall experience is consistently positive, with many finding it a favorite sector.
"This was such a great place to boulder. There weren't as much wasps as there are at Bas. On the last day there were horseflies though. The routes are great and very rewarding. They are all graded at the appropriate level in my opinion, although in Bleau you shouldn't focus on the grading but just climb the thing. My favorite was 30 red!"

"Fab spot. So much variety. Favourite spot in Fontainebleau for bouldering"
Hattie Hamzelou
"A standout sector without doubt, yet classics can be climbed in piece and quiet further back as few visitors get more than 2 minutes from the car park. All circuits provide quality throughout from an excellent orange circuit with surprising slab challenges to the fully committing 50 problem white circuit. The off piste problems offer an impressive selection at all grades to 7c+."
