Arnarstapi is a tini and beautifully situated fishing hamlet below Mt. Stapafell, on the shore of an encircled harbour where small fishing boats unload their catch. A walk along the cliffs on the shore, starting from the harbour, leads to a series of interesting sights. The cliffs on the coast are pitted with caves, some with blowholes on the roof and sheets of spray rise to a great hight when a gale is blowing. Offshore lie great craggy rocks surrounded by boiling surf. An interesting and picturesque sculptured arch rises on the shore below the lava encircled harbour.
