Route Overview

The route to Stob Coire Sgreamhach begins at the Three Sisters car park (NN185565), situated just off the A82. From here, the path leads into the Lost Valley, a hidden glen nestled between the towering ridges of Beinn Fhada and Gearr Aonach. This valley, once used by the MacDonalds of Glencoe to conceal stolen cattle, is a flat, rocky meadow surrounded by dramatic cliffs. The ascent continues steeply through boulderfields, craggy terrain, and a final rocky scramble to the summit of Stob Coire Sgreamhach.

The full return route covers approximately 10 kilometres with an elevation gain of 1,050 to 1,300 metres, depending on the exact path taken. Most walkers complete the round trip in 6 to 9 hours. This is a strenuous walk requiring a good level of fitness, confident scrambling skills, and a keen eye for navigation - especially in poor visibility.

The Walk

Stage 1: Entering the Lost Valley

From the Three Sisters car park, carefully cross the A82 and locate the signposted path leading into Coire Gabhail. The initial section climbs steeply through birch woodland, with the Allt Coire Gabhail burn cascading beside you. The trail is rocky and often wet, so sturdy footwear is essential. After approximately 1 kilometre, you will encounter the first burn crossing (NN173564), where stepping stones provide passage - take care here, as the rocks can be slippery.

Continue climbing until you reach a second crossing (NN169558). At this point, avoid the common mistake of following the burn straight ahead. Instead, take the path to the left, which leads towards the heart of the Lost Valley. The entrance to the valley is marked by a narrow gorge, opening out dramatically into a flat, rocky expanse at NN168555. Here, surrounded by towering cliffs, you will find one of Glencoe’s most atmospheric locations - a perfect spot for a short rest, with the valley’s infamous history adding to its allure.

Stage 2: Climbing to the Bealach

From the valley floor, cross the rocky terrain and trend right, following the faint path along the north bank of the Allt Coire Gabhail. As the path climbs out of the valley, it enters a steeper gorge-like section. The ascent here is challenging, gaining around 250 metres over the next kilometre on a mixture of scree and boulders. Concentration is key, as the trail becomes less defined.

Eventually, you will reach a bealach (mountain pass) at approximately NN162551. From this vantage point, the views open up across Glencoe and beyond, rewarding your efforts thus far. Take a moment to catch your breath and prepare for the final push to the summit.

Stage 3: Final Ascent to Stob Coire Sgreamhach

The final ascent to Stob Coire Sgreamhach is a steep, rocky climb with some scrambling required. Hands-on moves may be necessary near the top, particularly at a feature known as the "bad step". This section can be tricky, especially in snowy or icy conditions, so take your time and assess your route carefully. In clear weather, the summit provides panoramic views over Glencoe, with the neighbouring peak of Bidean nam Bian dominating the skyline. The effort is well worth it, as the sense of achievement and the vistas are truly spectacular.

Getting There and Parking

The Three Sisters car park on the A82 (NN185565) serves as the starting point for this walk. Arrive early, as spaces fill quickly, especially in peak season and on weekends. If the car park is full, consider parking at the larger lot near the Clachaig Inn, although this will add extra distance to your walk. Public transport options to Glencoe are limited, but buses run along the A82, with stops near the car park.

Be sure to check the weather forecast from reliable sources like MWIS before setting off. The upper sections of the route are exposed to sudden weather changes, and snow or ice can persist well into spring.
