Eldborg Crater Loop is best planned as a 6.6 km out-and-back day walk, not a true loop, to Eldborg scoria crater in Hnappadalur on the eastern edge of West Iceland's Snæfellsnes Peninsula. Starting at Snorrastaðir farm, the marked path crosses old lava and grassland to the crater, then climbs steep rocky steps with fixed chains to the rim. It suits hikers wanting a short, easy Iceland volcano walk, provided they are comfortable on rough lava and high steps. See more routes in Iceland.

Route Overview

Start and finish at the Snorrastaðir farm service area, reached by a short side road off Road 54, Snæfellsnesvegur. From the car park, follow the marked path and cairns across grass and an old lava field towards Eldborg. The crater rim is roughly 3 km each way from the trailhead; you return by the same path. Snorrastaðir is about 38 km from Borgarnes and 112 km from Reykjavik, so this is a straightforward half-day stop for a West Iceland road trip. If you want another Icelandic crater walk, compare it with Hverfjall Crater Loop; for a harder West Iceland day hike, see the Glymur Waterfall Trail.

Eldborg’s volcanic history

Eldborg means “Fortress of Fire”, a fitting name for its fortress-like ring of welded scoria. The crater formed in fissure eruptions on the boundary of Snæfellsnes and Mýrar, with volcanic activity estimated at 5,000–8,000 years ago. Eldborg is the largest of about five craters on the same eruptive fissure and has been protected as a natural monument since 1974. Today it is one of West Iceland’s best-known volcanic landmarks.

Notable highlights

Eldborg scoria crater: The oval crater is about 250 m long, 180 m wide and 50 m deep, with a rim rising roughly 60 m above the surrounding lava.
Chained final climb: Fixed chains help on the steep rocky steps up to the rim, the only hands-on section of an otherwise gentle walk.
Rim panorama: In clear weather, the crater rim gives wide views across Hnappadalur and Mýrar, towards Snæfellsjökull and Reykjanes.
Lava-field approach: The path crosses old vegetated lava and grassland between Snorrastaðir farm and the crater, with rougher lava near the base.
Protected volcanic site: Eldborg is the largest of about five craters on its fissure and has been a protected natural monument since 1974.

Challenges to expect

The walk is rated easy, but it is not a smooth path. Expect small and large rocks, gravel, scoria and rough lava, especially near the crater. The final climb to the rim is steep, with high rocky steps and fixed chains; avoid it in wet, icy or snow-covered conditions. Navigation is by marked path and cairns, and the crater is protected, so stay on the route.
