About the region

Discover Mull & the Small Isles

Mull and the Small Isles bring together some of the most varied island walking in Scotland. Mull provides the scale, with long sea lochs, an intricate coastline and mountains rising directly from the Atlantic. Rum supplies the drama, while Eigg, Muck and Canna prove that a hill need not be particularly high to dominate an entire island.

Ben More is the region’s highest summit and the only island Munro outside Skye. The direct ascent begins near sea level beside Loch na Keal, while the harder approach over Beinn Fhada and A Chioch adds rocky ridges and exposed scrambling. Elsewhere on Mull, Dun da Ghaoithe overlooks the Sound of Mull and Beinn Talaidh rises as a striking cone above Glen Forsa.

Across the water, the Rum Cuillin form one of Scotland’s finest compact mountain ranges. Their complete traverse crosses Hallival, Askival, Trallval and Ainshval in a long succession of steep slopes, narrow ridges and rough volcanic rock.

Eigg is defined by the unmistakable pitchstone ridge of An Sgurr. Muck offers gentle coastal hills and wide views, while Canna combines grassy heights with basalt cliffs and sea stacks. These are landscapes shaped by volcanoes, glaciers and the Atlantic—and exploring them still depends heavily on ferries, weather and sensible planning.

The Island Mountain Legacy

Ben More

Mull’s solitary Munro

Rising 966m directly above Loch na Keal, Ben More is the only Munro on a Scottish island outside Skye and the natural centrepiece of walking on Mull.

The Rum Cuillin

21km mountain traverse

Askival, Ainshval, Trallval and the surrounding peaks create a demanding island ridge with 1,902m of ascent and extensive scrambling.

An Sgurr

Eigg’s volcanic backbone

This 393m pitchstone ridge began as lava filling an ancient valley. The softer surrounding rock eroded away, leaving Eigg’s unmistakable summit standing above the island.

When to visit

Spring

March – May

Longer days and cooler conditions suit the bigger mountain routes. Puffins, seabirds and other summer visitors begin returning to the coasts.

Best for: Clear ridges, wildlife and quieter islands

Summer

June – August

The longest days provide enough time for serious ridge traverses. Ferries are more frequent, although midges can be fierce on sheltered and damp ground.

Best for: The Rum Cuillin and island-hopping

Autumn

September – November

Cooler conditions and fewer visitors make early autumn particularly rewarding. Ferry timetables reduce and daylight shortens as the season progresses.

Best for: Clear air and quieter trails

Winter

December – February

Snow, ice and Atlantic storms can turn the higher ridges into serious mountaineering terrain. Short days and disrupted ferries require flexible plans.

Best for: Experienced walkers and lower coastal routes
