Please note, in order to protect endangered wildlife, access to the chalk peaks in the commune of Haute-Isle is prohibited every year from March 1 to June 30 by prefectural decree. The paths to mass in Chantemesle are therefore cut off. Furthermore, following a collapse the previous summer, the Piton du Colombier is prohibited at all times for obvious safety reasons.

It is a medieval tower built in the 12th century to defend the castle and the river crossing. It is connected to the castle by a tunnel dug in the rock. The keep is 30 meters high and has four floors. It offers a panoramic view of the Seine valley and the Vexin regional natural park. You can visit the dungeon by climbing a staircase of 300 steps, or by taking an elevator installed in 2007. The dungeon is open to the public from April to November, from 10 a.m. to 6 p.m. It's a great place to enjoy a bit of history and adventure.
