þerna (1080m) is a summit belonging to Grýtubakkahreppur area in North Iceland.
It can be accessed from the end of the road (but involves a long flat valley to get to it).
Ski crampons can be necessary in the short middle ascent that gets quickly icy. The last part to get to the summit needs to be bootpacked (ice axe and crampons can be helpful). The final cross on the top welcomes you, with an amazing 360° views on the sea and surrounding valleys... Watch out for the strong wind at the summit!
