If you can get some a hold of some Velvia 50, which is a slide film, I have found the result of colour mountain photography to be spectacular. But a light meter is a must as it is very finicky as to exposure and tolerates little error. I actually really like the Provia as well but Velvia is better for landscapes.

Can't find Velvia or looking for something with more latitude? Kodak's Ektar 100 is wonderful. Unfortunately, not a lot else is available and neither is anywhere near as cheap as B&W film.
