X-island mountain walk

Sannox to Thundergay - Very good hill fitness is essential for this walk! The longest of the 2019 festival, this route traverses Arran from east to west, taking in the island’s second highest mountain Caisteal Abhail (The Castles) and stunning Loch na Davie, Loch Tanna and Coire Fhionn Lochan. It is a very long and physically demanding hill day, crossing some rough and boggy pathless terrain in the centre of the island which those with little experience may find arduous to negotiate, but the route does avoid any technically difficult sections.

Total Ascent

Walk Duration

Rough mountain paths with some steep ascents and descents, combined with pathless sections across rough and boggy moorland  

Technical Rating
Easy scrambling, elements of exposure, some rough terrain.

Endurance Rating
Sustained steep ascents and descents, stamina and perseverance essential to cover long distances. Have you recently walked up (and down) a mountain of over 1000m (3000ft) in height within 8 hours without physical distress! Are you generally fitter than the majority of your peers? If your answer is "No", we'd guess you'd be happier doing a walk rated a level lower than the one you’ve just read! As noted previously, we're into FUN so we don't want you to miss out by overdoing it.

 | Walk description

Starting at Sannox on Arran’s east coast, the path follows the murmuring Sannox burn all the way to the head of the glen, with the impressive north wall of Cir Mhor looming above.
After faintly climbing into Coire na h-Uaimh, the path steeply crests Hunter’s Ridge, then sweeps upwards to the towering granite crenellations of the Castles. After a well-earned rest, a gentle descent leads to Carn Mòr.
Pathless terrain now lies ahead, tramping down Carn Mòr’s west ridge to remote Loch na Davie, the water source for Arran whisky. From there, the twin summits of Beinn Tarsuinn are gained, affording stunning vistas into watery Glen Iorsa and a panorama of the Arran mountains. Losing height once more, the next waypoint is lonely Loch Tanna at the head of Glen Catacol.
From there, the path winds its way up the west side of the glen to the col between Beinn Bhreac and Meall nan Damh, then descends to scenic Coirein Lochain where there may be a chance to cool weary feet with a wee paddle in the loch.
Finally, a good path follows the tumbling stream of Uisge Soluis Mhòir down to the hamlet of Thundergay on the west coast, thus completing the traverse of the island.
