Why it's Wildland
8.0A hard coastal journey to sea arches beneath cliffs on Mull’s south coast, with Nun’s Cave and waterfalls along the way.
Carsaig Arches stand out for the combination of dramatic coastal geology and a genuinely challenging approach. This is not a casual viewpoint stroll: the sourced route is about eight miles, with rocky, sometimes narrow paths and exposed drops. The journey itself—past waterfalls and Nun’s Cave—is part of the experience.

The experience
A strenuous out-and-back coastal walk from Carsaig Pier to the arches. The supplied route guide gives about 8 miles and 6 hours, graded hard, over rocky, narrow and sometimes indistinct paths. Do not treat this as a simple sightseeing stop.
Things to do
Reach the sea arches
Walk the coastal route from Carsaig Pier towards the natural sea-arch formations. The path is described as rocky and uneven, with exposed sections; do not continue where conditions feel unsafe.
About 6 hours for the full return walk
Visit Nun’s Cave
A shallow cave described by the local guide as sandstone topped with basalt columns. The same guide reports religious carvings and relates, as a belief rather than established fact, that nuns fleeing Iona Abbey during the Reformation may have taken refuge here.
About one hour’s walk from the start, according to the guide
Look for waterfalls and coastal wildlife
Waterfalls, seabirds and wild goats are mentioned in the supplied sources; seals may sometimes be seen, but sightings are not guaranteed.
