The Arnarstapi to Hellnar walk is one of the best coastal walks in Iceland, following the lava cliffs on the south side of the Snæfellsnes peninsula. The route is about 2–2.5 km each way, 4–5 km return, and takes 1–1.5 hours, with only 20 m of ascent and a highest point of 40 m. It is easy and mostly flat, but with so much to look at, it tends to take longer than expected.
The path runs along a protected stretch of coast where the sea has carved arches, caves and columns into old lava. You pass Gatklettur, the arched rock at Arnarstapi, and cliffs where fulmars and kittiwakes nest, before reaching the tiny harbour at Hellnar with its sea cave, Baðstofa. Snæfellsjökull glacier rises behind the whole route on clear days. Stay on the marked path: the cliffs are undercut and the area is a nature reserve.
Highlights
- Gatklettur stone arch and the harbour at Arnarstapi
- Basalt columns, sea caves and blowholes
- Nesting kittiwakes and fulmars on the cliffs in summer
- The small harbour and Baðstofa sea cave at Hellnar
- Views of Snæfellsjökull glacier inland
The route
Arnarstapi cliffs and harbour
Begin near the large stone statue of Bárður Snæfellsás in Arnarstapi and follow the cliff path toward the harbour. Here the coast is full of arches, caves and basalt columns, with Gatklettur the best known. In summer the ledges are busy with nesting seabirds. Keep behind the barriers where they exist, and well back from edges elsewhere.
Along the lava coast to Hellnar
The path then follows the shoreline over moss-covered lava, with the sea on one side and Snæfellsjökull on the other. It is clear and mostly flat, with a few rocky or muddy patches. At Hellnar you arrive at a small harbour and the Baðstofa sea cave, known for the colours of the rock inside at the right light.
Getting to the trailhead
Arnarstapi is on the south coast of Snæfellsnes, about 2.5 hours' drive from Reykjavík via Borgarnes and Route 54, then Route 574. Both villages have parking. If you do not want to walk back, arrange a car shuttle; otherwise many people simply return along the same path. Public transport on Snæfellsnes is limited, so a car or tour is the practical option.
Where to stay
Arnarstapi and Hellnar have guesthouses, a hotel and a campsite, though they fill quickly in summer. Other options are along the south coast of the peninsula and in towns such as Ólafsvík, Grundarfjörður and Stykkishólmur.
Best time to hike
The walk is possible all year. May to August is best for nesting seabirds and long days, though this is also the busiest period. In winter the path can be icy and windy, but the coast with snow and low sun is very atmospheric. Always check the forecast for wind and big waves.
Safety
The cliffs are undercut and can collapse; stay on the path and keep well back from the edge, especially in wind or with children. Large waves can surge into coves and caves. In winter the path can be icy. Respect nesting birds and do not approach the ledges. Check vedur.is and SafeTravel.is before you go, and call 112 in an emergency.
