Ideally, you should take 3-5 days to reach the summit of Damavand (5610 m). It can be done in as little as two days. However, that is not advisable if you haven’t climbed it before.
While the trek is not technically that difficult, the altitude gain should not be underestimated. The air gets pretty thin up there. You’ll thank yourself later for taking the time to properly acclimatize, either with acclimatization hikes or by staying in a mountain hut for an extra night.
There is a lot of beautiful nature to be seen here, so if you wish you can add more days to your trek. One great option is to visit the Abe Garm Larijan hot springs in a nearby Lar Valley village. There you can rest your tired legs and experience the local culture.
