Loch Avon Circuit

Overview

This is a committing high‑mountain loop from the Cairngorm Ski Centre car park that drops into the spectacular glacial trench of Loch Avon (often pronounced “A’an”) before clawing back to the plateau. Expect sweeping, barren views, steep corries, dramatic waterfalls, and a true sense of remoteness. Variants sometimes include a detour to Ben Macdui and/or a loch‑shore visit to the famous Shelter Stone. Total distance for recognized circuits varies widely — roughly 8.4–12.5 miles depending on the exact line — and the day feels bigger than the mileage suggests due to exposure, rough ground, and navigation challenges.

Trail Experience

The plateau sections are windy, exposed, and unmarked in places. The crux for most people is the descent to and climb out of the Loch Avon basin: users describe near‑vertical, loose ground by a waterfall where the path fades, with hands‑on scrambling and poor footing. It’s serious, especially in the wet or when streams are running high. Around the loch you’ll find boulder fields and that signature amphitheatre of cliffs. Wildlife here skews arctic‑alpine: look for ptarmigan and mountain hares on higher ground, with deer moving through the basins.

Who Will Love It (and Who Won’t)

Experienced hillwalkers who relish rough, steep mountain terrain and real route‑finding will have a field day; the scenery is top‑tier. If exposure, scrambling, or ambiguous paths aren’t your thing, this won’t be a fun introduction to the Cairngorms. Consider a viewpoint approach from Glenmore if you want the loch without committing to the steep descent/ascent.

Logistics

Start and finish at the Cairngorm Ski Centre car park above Glenmore (charges apply). A bus can reach the car park. Dogs have been reported on this loop, but only bring a mountain‑savvy pup you can keep tightly controlled — the ground is steep, loose, and exposed in key sections.

Best Time to Hike

Late spring through early autumn in clear, dry weather is the sweet spot. Avoid or rethink the circuit after heavy rain or melt when rivers are running high, and treat winter/shoulder‑season snow and ice as a mountaineering problem. Even in summer, expect rapid weather shifts and poor visibility.

Tips

• Carry and know how to use a map and compass; don’t rely on phone signal.
• If the waterfall line into/out of the loch looks unsafe, turn around and choose a different variant or save it for a better day.
• Pack for wind and cold even in warm months; this is exposed, high‑plateau walking.

Length note: Distance varies by variant (about 8.4–12.5 miles total). The figure below reflects a fuller circuit rather than the shortest option.
