Hello! I really would like to come to this -- I live in Paris and want to take the RER and a bike to get there, and go back in the evening. Do you have more details about where and when to meet on the day? I've explored a little bit around Fontainebleau but never done a climbing day, so it'll be my first time. Thank you!!
No Climbing Today!

Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
