This is a prime line in the area that looks like a walk in the park but ends up being quite the satisfactory little struggle :) The beginning is straightforward with a heelhook here and there, after which the fun part starts. There are a few ways to move along the slopers at the top and get you pumped in seconds. The topout feels like a true reward. Some throw a high heel to the right before mantling out, others go left leg first.
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.
