Glen Nevis

Where it sits. Glen Nevis runs south-east from the edge of Fort William, wedged between the mass of Ben Nevis on its northern side and the long Mamores ridge to the south. A single road follows the Water of Nevis for about seven miles before ending at a car park below the Nevis Gorge; beyond that point the glen continues on foot only. The lower glen is broad, wooded and pastoral, with fields, a campsite, a youth hostel and the Ben Nevis Visitor Centre near Achintee. The upper glen narrows sharply, the road becomes single track, and the scenery changes from farmland to something much rawer.

The mountain above it. Ben Nevis, at 1,345 m the highest ground in the British Isles, dominates everything here, though the summit is invisible from most of the glen. The standard route to the top — the Mountain Track, still widely called the Pony Track from its origins as a path built in 1883 to serve a meteorological observatory on the summit — starts either at Achintee in the glen or at the visitor centre across the footbridge. That observatory operated from 1883 to 1904, and its ruins still stand on the summit plateau beside the emergency shelter. The mountain's other face, the enormous north-east cliff, is one of the most important climbing arenas in Europe and is reached from the opposite side of the hill, not from Glen Nevis.

On screen. Glen Nevis has been a working film location for four decades. A Hagrid's hut set was constructed here for Harry Potter and the Goblet of Fire (2005) and used again for Half-Blood Prince (2009) — a different structure in a different glen from the earlier hut built in Glen Coe for Prisoner of Azkaban (2004). The flat meadow at Steall, at the head of the glen beyond the gorge, held the Triwizard Tournament encampment for Goblet of Fire, with the 120-metre Steall waterfall visible behind. Earlier, the lower glen supplied the main Scottish village and battle locations for Braveheart (1995), and it had already appeared in Highlander (1986) and Rob Roy (1995). None of the sets remain; the fields are back in agricultural use and nothing is signposted.

What you actually see today. Working up the glen, the sequence is: farmland and the visitor centre; the woods and the Lower Falls at Polldubh, a popular swimming and picnic spot where the river drops over granite ledges; the single-track section beneath the steep slabs of Polldubh Crags, a long-established rock-climbing venue with hundreds of short routes; then the road end. From there the gorge path leads in 40 minutes to the Steall meadow and its waterfall. Walkers also start the Mamores traverse here, and the glen forms the final approach of the West Highland Way, which comes over the shoulder from Kinlochleven and drops into the upper glen before running down to Fort William.

Getting there and timing. The glen road leaves the A82 at the northern end of Fort William and is signposted for Ben Nevis. A seasonal bus runs partway up; there is no service to the road end. Driving takes 20 to 25 minutes to the far car park, longer in summer when the single-track section forces frequent waits in passing places. Parking is genuinely tight: the upper car park is small and typically full by mid-morning from June to September, and there is no legitimate roadside overflow. Early starts solve most of it. May and June give long daylight and the best chance of settled weather; October brings colour along the river; winter turns the upper glen and the whole mountain into serious terrain requiring axe, crampons and navigation skill.

Practical notes. This is a place where the difference between the lower and upper glen matters for planning. The lower glen is easy, family-friendly ground with facilities, a café at the visitor centre, level paths and picnic sites by the river. Above the Lower Falls, the character shifts: the gorge path is rocky and exposed above a drop, unsuitable for wheelchairs or small children, and the wire bridge beyond the meadow is a genuine obstacle. The river looks inviting and drowns people — it rises rapidly after rain on the hill, the pools are deep and cold, and there are submerged undercuts at the Lower Falls.

One more caution. Ben Nevis attracts well over a hundred thousand ascents a year, a large share by people underestimating it. The summit plateau is featureless, frequently in cloud, holds snow into early summer, and has cliffs on two sides with a descent line that requires accurate compass bearings. Mountain rescue callouts from this glen are among the highest in Britain. If the plan is the mountain rather than the glen, treat it as a full day, carry map, compass, food and warm layers regardless of the forecast in town, and turn back early rather than late.
