The Lar valley lies in Northeast of Tehran on Western slopes of Damavand. Its great biodiversity has made it one of the major national parks of Iran. It’s the habitat of many animals and plants, specially some rare and endemic species of Iran. The trail starts from SW face of Damavand toward the North at 3000 m Elevation. By decreasing the elevation toward the west along a minor valley ending to Lar valley, the route comes alongside the Lar river. You should pass through river several times. After spending two nights with nomads and complete survey of Lar valley we return to civilization after 2 days of being in Mother Earth’s wild from Garmabdar route.
