Βoufanis gorge is formed southeast of Selakano and finishes between the villages Chirstos and Metaxohori of Viannos Province. The gorge is also known as:
- Selakano Gorge after the Wood Selakano at its starting point.
- Vultures Gorge after the birds of prey flying above it.
- Parsas Gorge after the old name of village Metaxochori.
- Psoriaris Gorge after the river Psoriaris that flows inside it.
Hiking is usually done by the old path that connects Selakano with Metaxochori and it passes high and parallel to its bed. Hiking in the bedside is quite tough, as there are small waterfalls, while in winter it's impossible to cross it without getting wet.
