29km Rando des 6 châteaux en Vallée de Chevreuse

A full-day loop from the Saint-Rémy-lès-Chevreuse station (RER B terminus) through the woods, valleys and villages of the Haute Vallée de Chevreuse, passing six châteaux along the way.

The idea is to meet at Saint-Rémy-lès-Chevreuses RER B Station at 08:23. I'll personally be taking the 8:02 RER B train with destination Saint-Rémy-lès-Chevreuse from Massy - Palaiseau. If you wanna join me on that train, you'll find me at the backmost wagon wearing hiking gear.

Distance: about 29.5 km
Elevation gain (D+): around ~750, but probably a bit less
Pace: 5 km/h
- Duration: around 6h40 with a lunch break

What to bring
- Hiking shoes and clothes
- 2L of water
- Packed lunch
