The valley was formed by a glacier that carved the base, followed by a massive landslide that dammed the drainage, creating the flat floor.
The Clan MacDonald utilized this location to conceal rustled livestock following raids on neighboring territories.
The name Coire Gabhail translates from Gaelic as 'Valley of the Goats'.
The route requires crossing the River Coe, which can become impassable during periods of heavy rainfall.
It sits at the heart of the Bidean nam Bian massif, which contains the highest point in the former county of Argyll.
The entrance to the glen is partially hidden from the main road by a gorge and natural rock formations.
Hidden Glen, locally known as the Lost Valley or Coire Gabhail, is a hanging valley situated deep within the Bidean nam Bian massif in Glencoe. The glen was formed by a rockfall that blocked the valley floor, creating a flat basin suspended above the main Glencoe valley. It served as a historical hiding spot for the Clan MacDonald, who used the concealed location to hide stolen cattle. Accessing the glen requires navigating a rocky path that crosses the River Coe and involves a section of mild scrambling. The surrounding landscape consists of steep mountain walls and dramatic crags typical of the West Highlands. The site is a popular destination for hikers looking to explore the rugged geography of the Three Sisters. The terrain is largely composed of glacial debris and loose scree slopes. It remains an unprotected wilderness area without marked facilities or modern infrastructure.
The elevated vantage point looking back down into the basin from the rocky threshold at the valley entrance.
Wear boots with high ankle support and reliable grip, as the path involves uneven stone, loose gravel, and stream crossings.
Carry a physical map and compass, as mobile signal is unreliable and weather conditions in the glen shift rapidly.
Trekking poles are recommended for stability on the steep, rocky descent and the scramble sections.
Do not attempt the hike in high winds or heavy rain as the river crossing becomes dangerous and the path slippery.
Practice leave-no-trace principles, as the area is a remote ecological site; avoid disturbing local livestock or wildlife.
