Beautiful rock gate made of red sandstone... From here the path continues up to the Rocher de Mutzig... it's best to come at off-peak times, then you have the rock to yourself...

The wooden hut is beautifully situated in a clearing... unfortunately it is closed, but the canopy offers protection against rain
