What is the best way of ascending to the summit?

The Damavand Mountain is a volcanic conical mountain with sixteen crests to reach the summit. But out of the sixteen crests, only four of the crests have safe haven or shelters. Out of the four crests ONLY two of the crests have support to the ascenders. The southern crest passes through Polur village, and the path for the Northern crests will be passing through the southern crest.  Thus the path for the southern crests is the most commonly used route and chosen for its fewer gradients for trekking which makes it the ideal choice to ascending to the summit. The south ascending summit you will face less obstacles or large inclines and having access to shelter in 4,250 meters.
