The village of Shorzha has a tiny clinic, but you should watch for snakes and other dangers as the facility may not be able to treat you, and a real hospital can take time to reach.

Part of the area is a national preserve and technically requires permits to visit, a requirement that seems to have never been enforced. The boundaries of the preserve are not marked, so in general visitors need to be extra sensitive if they leave the roads and hike or camp in the countryside.
