Grey Mare’s Tail is a 60-metre hanging valley waterfall near to Moffat in southern Scotland. The fall is produced by the Tail Burn flowing from Loch Skeen cascading into the Moffat Water in the lower valley below. The surrounding area forms the Grey Mare’s Tail Nature Reserve, owned by the National Trust for Scotland.

The wild and rugged landscape of this National Trust for Scotland reserve in Dumfries & Galloway is a taste of the highlands in the lowlands. The 60m Grey Mare’s Tail waterfall is the UK’s fifth highest; a walk up alongside it will eventually bring you to isolated Loch Skeen and Britain’s rarest native freshwater fish, the vendace.

Continue climbing to the top of White Coomb (821m), Dumfriesshire’s highest peak for inspirational views to the Scottish Borders and even beyond if the weather goes in your favour. Look out for peregrine falcons, osprey and, if you’re lucky, golden eagle, which have been reintroduced in recent years.
