The Hotel and it's neighbourhod will give you many ideas for photos. Sometimes, moving just a few steps, the landscape changes completely. The light in Arolla is special because of the altitude and the abscence of pollution. Even with bad weather (this very seldom happens!) it is possible to make nice pictures with the fog and the clouds.

For amateur astronoms, the watching of the stars is magnificient because of the very high transparency of the air due to altitude. The number of stars visible by the naked eye is a lot higher than in the plain. Also there is no halo due to public lighting. Don't forget your sky map home.
