About Hverfjall Waterfall
Hverfjall Crater is in northern Iceland, located to the east of Mývatn. It is a roughly circular volcanic crater of about 1,300 m (4,265.1 ft) diameter and 140 m (459.3 ft) deep. It stands at an elevation of 420 m (1,378 ft) and is one of the largest craters in the world.
It is known as a striking sight, and was created nearly 2,800 years during a small but powerful eruption. The cinder cones within it rise to a height of about 200 m (656.1 ft).
The rim of the crater is only accessible by two paths, one from the north west and the other from the south. No other routes may be used to climb or descend the crater.
