Woke up with a hangover from drinking a bottle of wine by myself in the hotel restaurant (thought I ordered a glass but oh well). Thick clouds in the morning got me off route. Finally got up to the ridge from the southwest and promptly cornered myself on loose Class 4-5 stuff. Backtracked and found a notch over to the other side where it was easy Class 3 to the summit. Will submit a trip report when I get all the Icelandic peaks I climbed submitted.
