Hellnar is a tiny, ancient fishing village at the western end of the Arnarstapi coastal walk, with a harbour sheltered by a natural basalt breakwater and a small cafe that serves the best soup in Iceland on cold afternoons. The village is old by Icelandic standards — fishing was practised here for centuries before the peninsula's population shifted inland — and the arrangement of old turf-walled fishing huts alongside the modern cafe has a genuine lived-in quality.
The cliff area around Hellnar harbour contains a sea cave called Baðstofa where seabirds nest in huge numbers; the cave can be peered into from the path. The landscape between Hellnar and the base of the glacier is a lava field with a character quite different from the cliff walk — dark, chunky aa lava from eruptions a few thousand years ago, with mosses beginning to colonise the cracks and hollows. The Snæfellsjökull National Park visitor centre is nearby, with information on the park's geology, ecology, and hiking routes.
