Cloud forest is a type of rain forest which grows high in mountains - literally in the clouds - particularly on ridges, where the airstream is pushed up and causes clouds to form. Trees which would be tens of metres high lower down grow stunted - when I have seen cloud forest, the trees were only eight of so feet high - and the moisture from the clouds supports a rich epihpyte flora - so the trees are covered in mosses, ferns and orchids.

Cloud forest is fascinating (though cold); the stunted trees give the appearance of a dreamlike or fantasy forest - you expect to see goblins or elves (or hobbits...) walking thorugh it.
