Whitebeams & Wildlife of the Western Hills

Arran is home to three species of tree which do not occur anywhere else in the world, the Arran Whitebeam (Sorbus arranensis), Cut-leaved Whitebeam (Sorbus pseudofennica) and Catacol Whitebeam (Sorbus pseudomeinichii). This walk gives an opportunity to learn about these trees, some of rarest in the world, as well as experiencing a range of mountain wildlife.

 | Walk description

Starting at Catacol, this route follows the path up Glen Catacol and into Gleann Diomhan, looking out for wildlife along the way.

In Gleann Diomhan some time will be spent chatting about the Arran Whitebeams, Scotland’s rarest native trees. Whilst the Arran Whitebeam was first recorded in 1897, the Catacol Whitebeam was only found as recently as 2007. In global terms, these trees are classed as dangerously close to extinction.

From the head of Gleann Diomhan, the route heads off-path and steeply up onto Beinn Tarsuinn, the highest point of the walk at 527m, and haunt of golden plover, birds of prey and red deer in the wild and remote western heart of Arran’s hills.

Continuing across boggy pathless terrain, the walk then descends to Loch Tanna, nestled under the scree slopes of Beinn Bhreac. Some early sundew and wispy cotton grasses may be encountered on its boggy shores. The route then rises again to reach the coll between Meall Bhig and Meall Bhreac before the descent to Coire Fhionn Lochan, a great place for a paddle on a sunny day.

Heading down the path from the lochan, wonderful views over to Kintyre and beyond can be enjoyed before reaching civilisation again at Thundergay.
