Wear sturdy hiking boots and bring weather protection, as conditions at the summit are much harsher than in the valleys below. Plan your climb for daytime to reach the peak and descend with enough light remaining.

From the summit you can see multiple vegetation zones at once, ranging from alpine meadows to semi-arid areas. This view shows how dramatically the landscape changes with elevation across the Armenian highlands.
