Total Ascent

Walk Duration

Rough, boggy and muddy hill paths with some steep ascents and descents.

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

The walk starts at the car park opposite the Sandwich Station in Lochranza and follows the public road for a mile before turning off into Gleann Easan Biorach.

A rough path ascends this scenic valley past several waterfalls, leading into the wild and remote heart of north Arran. At the head of the glen lies Loch na Davie, the water source for Arran Whisky, with views opening up across the adjacent mountains and into watery Glen Iorsa. Contouring round to Gleann Diomhan, home of the endemic Arran whitebeams, the path now descends along a picturesque burn gorge to Glen Catacol and finally, the village of the same name.

The route then climbs up again to follow the historic Postman’s Path above the old sea cliff back to Lochranza, affording spectacular views across the Kilbrannan Sound.
