Perhaps the purest form of mountaineering, a mixture of rough walking and easy climbing. Learn scrambling skills or be guided up the classics of the Highlands e.g.

The Cuillin of Skye

Curved Ridge, Glencoe

Aonach Eagach, Glencoe

Tower Ridge, Ben Nevis


Rock Climbing

The Highlands are blessed with a huge variety of fantastic glen, mountain and coastal rock-climbing venues. Take advantage of high-quality instruction to boost your skills, whether you're new to outdoor climbing, want to learn to lead on trad gear, or learn the skills needed to enjoy big multi-pitch adventures. Or simply enjoy being guided up some of the Highland's classic climbs.


Navigation courses

Smartphones and GPS are great---until the batteries run out! Learn how to use a map and compass to find your way around the hills. Whether complete beginner, or experienced hillwalker, we can help you improve. We also offer all levels (Bronze, Silver & Gold) of the National Navigation Award Schemes (NNAS) for those wanting to evidence their learning.

Summer Walking

The scenery of the Scottish Highlands & Islands is world-renowned. Learn mountain skills or be guided on routes of your choices, whether the high Munros--Ben Nevis, Cairngorms, Glen Coe, Skye, Torridon--or the beautiful low-level glen and coastal walks.


Winter Walking

Snow and ice transform the Scottish hills into something quite magical, offering the perfect blend of accessibility, challenge and adventure. Learn the skills you need to operate safely in this season or simply be guided up some fabulous mountains.
