Ground Conditions: End of September and well into autumn. It has been a very hot summer, with serious fires in the Cairngorms centered around the area of Bynach More. Now, after some rain the ground is not as dry and there have been reports of the rivers being hard to cross. [September 2026]

Although Cairngorm and Ben Macdui are among the highest peaks in the UK, Cairngorm’s proximity to the ski infrastructure makes it readily accessible. In contrast, continuing on to Ben Macdui offers a true wilderness experience, leaving the developed area far behind. Walkers should note that despite nearby infrastructure, the Cairngorm plateau remains one of the most exposed and challenging mountain environments in the UK, requiring careful preparation and respect.

Section 1: Coire Cas Car Park to Cairngorm Summit
Distance: 3 kms. | Ascent: 640 m. | Estimated Time: 2 hrs. 10 min.
The main ski area car park at Coire Cas, situated at the end of the access road, is easily identified and busy year-round with skiers, mountaineers, and funicular visitors. On peak ski days, an early arrival is recommended, though space is generally sufficient at other times.
Multiple paths ascend from Coire Cas through the ski area to the summit. During winter conditions, walkers should remain along the edge of the pistes adjacent to the snow fences for safety and courtesy to skiers.

  • From the car park, follow the road past the Day Lodge and pass beneath the funicular railway.
  • Ascend the path toward Windy Ridge (Sròn an Aonaich) and continue along the ridge crest to the Ptarmigan Restaurant.
  • Follow the well-marked path beyond the restaurant to the summit.
The summit of Cairngorm is distinctive, marked by a prominent cairn and an automatic weather station.

Section 2: Cairngorm Summit to Ben Macdui
Distance: 6 kms. | Ascent: 170 m. | Estimated Time: 2 hrs. 10 min.

  • From the summit of Cairngorm, descend west along the rim of Coire Cas and continue around the rim of Coire an t-Sneachda.
  • Shortly before the path ascends toward Cairn Lochan, take the track branching southwest toward Lochan Buidhe.

The broad summit of Ben Macdui is easily recognized by its large cairn and triangulation pillar.
