Grey Mare's Tail

The Grey Mare's Tail is one of Britain's highest waterfalls, a long white ribbon of the Tail Burn plunging around sixty metres down a steep glen in the hills north-east of Moffat. Above it sits the hidden hanging valley of Loch Skeen, ringed by crags. It is a dramatic, compact subject in the Dumfries and Galloway uplands. The car park sits right at the foot of the falls, so the main cascade is immediately accessible, and a steep path climbs beside it towards the loch for higher vantage points. Drone footage of the full drop, framed by the craggy glen walls, is genuinely striking, and the loch above rewards those who carry their kit up. Importantly, this is a National Trust for Scotland reserve, so you must seek NTS consent before taking off or landing; that makes it a caution site rather than a free-for-all. The reserve is also home to peregrines and feral goats, so fly with care and avoid disturbing wildlife. There is no FRZ in this remote spot. The glen is steep-sided and funnels wind, and the path itself is genuinely dangerous near the drops, so keep well back from the edge when piloting. Spring melt gives the fullest flow.
