Agulhas Negras and Pratileiras are the highest points in the park, and among the highest points in the whole country. The vegetation gets sparser the higher you go, so don't forget sunblock and a hat. The views are fabulous, especially in the dry season (May-Aug). Pratileiras is an easy climb but Agulhas Negras is a little tougher, and requires some effort, if not actual moutaineering skills. Due to an arson attack a few years ago, which resulted in a huge fire that destroyed most of the area's vegetation (it has since recovered), access is only possible with a registered guide or agency. These can be hired through the local pousadas (small hotels). Agencies usually provide their own 4x4 transport, probably the better option, because access is through a secondary gate very far from the main entrance and the access road is very rough.
