Hvannadalshnukur

Hvannadalshnukur is a peak on the northern rim of the Oraefajokull caldera and the highest point in Iceland at 2,110 metres - a figure set by a resurvey in 2005 that took nine metres off the long-quoted 2,119, because the older measurement had included snow and ice rather than rock. The climb is long rather than technical: fourteen to sixteen hours from sea level, roped for the crevassed sections, usually started around midnight to be on firm snow. Most parties go between April and June, when the snow bridges are sound and the days are long. Oraefajokull is an active volcano and its last eruption, in 1727, was preceded by one in 1362 that wiped out the district below.

What you actually see

• The country's highest point - 2,110 metres on a caldera rim.
• Nine metres lost to a resurvey - the 2005 measurement excluded snow and ice.
• A long day, not a technical one - fourteen to sixteen hours, roped for crevasses.
• An active volcano beneath - eruptions in 1362 and 1727.

When to go

April to June, when snow bridges hold and light is long. A full day.

Honest expectations

This needs glacier experience or a guide, crampons, rope and real fitness; it is not a walk. Trips turn back regularly for weather or snow conditions. There is nothing on the mountain - no huts, no shelter, no phone signal on much of it.
