The top of the craggy precipice Stóraklif is a treacherous 30-minute climb from behind the N1 petrol station at the harbour. The trail starts on the obvious 4WD track; as it gets steeper you’re ‘assisted’ by ropes and chains (but don’t trust them completely). If you can bear the terror, you'll get outstanding views. Further out on the pier, Heimaklettur is more perilous, with wild rickety ladders. Both are top puffin-breeding grounds. When rainy, slick or windy, neither is a good idea.
