Mallaig → Rum (Loch Scresort). Mon, Wed, Fri, Sat (Apr–Oct) in summer; Mon & Thu only (Nov–Mar) in winter. Book at least 28 days ahead. No cars permitted on Rum — foot passengers only. An overnight stay at Kinloch Castle bunkhouse or Dibidil bothy is strongly recommended.

Ainshval

Ainshval is the second-highest summit on Rum, the 781m southern peak of the Rum Cuillin ring. The mountain forms the natural pair with Askival on the ridge traverse — most parties tackle both on the same day. The Norse-derived name reflects the island's Viking heritage; many Rum hills carry old Norse names rather than Gaelic. From the summit the view sweeps across to Skye and along the rest of the Cuillin ring. A serious commitment because of the ferry-only access and the scrambling on the connecting ridge.

From Kinloch, walk the path south for around 4km to reach the col below Hallival. Climb Hallival, traverse the scrambling ridge south to Askival, then continue across Trollaval and Ainshval to complete the four-Corbett ring. The descent off Ainshval drops south-west into Glen Harris before turning back north via the loch-side estate track. Allow 10–12 hours for the full ring. For Ainshval alone (not the standard approach), start from Glen Harris and climb the south flank direct.

Terrain

The Rum Cuillin ring is a serious mountain day. Sustained Grade 2 scrambling between Hallival and Askival, mostly Grade 1 between Askival and Trollaval. The basalt is sharp and grippy in the dry, slick when wet. Glen Harris descent is rough underfoot with bog and boulder fields.

In winter

Winter on the Rum Cuillin is for experienced mountaineers — the scrambling becomes Grade I/II winter climbing, daylight is short, and the ferry from Mallaig runs only twice a week in winter. Most parties confine winter visits to the lower ground; the ring traverse is rare outside the May-to-September window.

Outside the SAIS network. No Scottish Avalanche Information Service forecast covers Ainshval. SAIS forecasts six areas only — Northern and Southern Cairngorms, Creag Meagaidh, Lochaber, Glencoe and Torridon — and this hill is outside all of them, so there is no avalanche forecast to read for it. In winter, use MWIS The Northwest Highlands ↗ for mountain weather, judge snow stability from first principles, and treat any cornice or wind-loaded slope with extra caution.

Before you go

Hillwalking carries real risk and the responsibility for any day on the hill is yours. Conditions in Scotland change fast and can differ sharply from the forecast — check the weather and the ground before you commit, turn back when the day stops working, and carry map and compass with the ability to use them rather than relying on a phone.

The distance, ascent and time shown on this page are editorial estimates for the usual line, not measurements from a recorded track — that is what the ~ means. Treat them as a rough shape of the day. Your own pace, the conditions and the exact line you take will all move them.

Mountain forecasts: MWIS and the Met Office mountain forecast. Access rights and responsibilities are set out in the Scottish Outdoor Access Code.

We check what we publish, but we cannot check the route on the day you walk it. Nothing here is a substitute for your own judgement.
