Grey Mare's Tail Waterfall, Moffat

A Majestic Cascade Shaped by Ice Age Forces

Grey Mare's Tail Waterfall is a spectacular natural feature carved by glacial erosion during the last Ice Age. The waterfall plunges approximately 60 meters (200 feet) from Loch Skeen, a remote upland loch perched high in the Southern Uplands. The meltwater cascades down a steep hanging valley into the Moffat Water Valley, creating a narrow, frothing white stream that resembles the tail of a grey mare, inspiring its evocative name. The geological formations around the waterfall showcase layered Silurian greywacke sandstone and mudstone, with visible ribs of hard rock interspersed with softer eroded sections. This dramatic landscape is an outstanding example of glacial landforms and ongoing natural processes that shaped the region millions of years ago.

Walking Trails and Scenic Experiences

Visitors can access Grey Mare's Tail from a nearby car park managed by the National Trust for Scotland, which charges a small fee. From there, well-maintained but sometimes steep paths lead to different viewpoints of the waterfall. A gentler trail follows the burn’s left side to the lower cascades, while a steeper, more challenging route ascends the right side to the upper plunge pools and ultimately to Loch Skeen. The full walk to Loch Skeen is about 2.8 miles (4.5 km) round trip and involves a significant climb, rewarding hikers with breathtaking vistas of the loch and surrounding peaks such as White Coomb and Lochcraig Head. Along the way, walkers encounter smaller waterfalls, diverse upland flora, and tranquil natural settings.

Wildlife and Natural Heritage

The Grey Mare's Tail area is a haven for wildlife enthusiasts. Rare upland plants thrive here, alongside sightings of peregrine falcons, ring ouzels, feral goats, and occasionally ospreys fishing in Loch Skeen. The loch itself is home to Britain’s rarest freshwater fish, the vendace. The burn and surrounding habitats also attract dippers and grey wagtails, adding to the rich biodiversity. The site is protected and managed to preserve its fragile ecosystems and geological significance.

Historical and Cultural Significance

Beyond its natural beauty, the area around Grey Mare's Tail holds a deep human history. Archaeological evidence points to Iron Age activity, and in the 17th century, Covenanters used nearby Watch Knowe as a strategic lookout to monitor government troop movements during turbulent times. The waterfall also inspired literary figures such as Sir Walter Scott, who referenced it in his poem "Marmion," calling it the "roaring linn." This cultural heritage adds a layer of storytelling to the dramatic landscape.
