Munro · Skye & The Small Isles

Blabheinn (Bla Bheinn)

Blà Bheinn (928m) — anglicised as Blaven — is the only Cuillin Munro separated from the main Black Cuillin ridge, standing in splendid isolation east of the main range above Loch Slapin. The hill is widely regarded as the finest viewpoint for photographing the Cuillin and offers a Cuillin scrambling experience without the navigation challenges of the main ridge. The summit ridge has two close tops with an airy traverse between them.

Standard route

Glen / path 30% · Steep corrie path 35% · Grade 1-2 summit scramble 35%

16km · 817m ascent · 4.6 hrs

Park at the small lay-by on the B8083 at the head of Loch Slapin (between Torrin and Kilmarie). Take the path west into Coire Uaigneich, then climb the steep south-east shoulder onto the summit ridge. The connecting move between the two summits involves Grade 2 scrambling on a short rocky step. Most parties take in both tops. Around 8km return with 940m of ascent — a short, steep day with technical interest at the top.

Terrain

The walk into Coire Uaigneich crosses wet heathery moor before the path climbs steep boulder slopes onto the south-east shoulder. Linking the two summit tops involves a short Grade 2 scramble on a rocky step. The high point is a small platform with a boulder set beside the cairn. Compass readings are unreliable on Skye's gabbro and basalt.

In winter

A serious Skye winter mountaineering objective. Under winter conditions the summit traverse becomes a Grade I/II climb. The Cuillin gabbro and basalt readily ice with verglas. The Coire Uaigneich approach holds avalanche-prone snow after westerly storms. Daylight is brief; the B8083 stays accessible in normal conditions. Few parties tackle Blà Bheinn in winter without rope work.
