The gorge of Agios Nikolaos, Gafaris or Rouvas is bounded by the peaks of Ambelakia from east and Samari from west. This is the most important gorge of Psiloritis and central Crete and took its name from the homonymous Byzantine church in the south entrance. This is an ecosystem with rich flora and fauna, smaller canyons and interesting geological formations and cliffs of rare beauty. It has a total length of 4 km with 2,7km being well-shaped by the Forest Service for soft activities such as hiking, mountaineering, rock climbing, naturalism and observation of wildlife in a truly unique environment. Unfortunately, a significant part of the beautiful forest of Rouvas, near the south entrance of the Gorge was destroyed by a major fire in 1994.
