Standard route
heather moorland 55% · grass slopes 35% · boggy ground 10%
A direct ascent from the A7 near Ewes climbs heather and forest edge for around 3 hours return. The summit can also be approached from Westerkirk in Eskdalemuir.
Terrain
Deep heather on the upper slopes — slow going off the fence-lines that thread across the hill. Forestry edges aid the lower approach.
In winter
Snow lingers in heather hollows but the south-facing aspect clears quickly after thaws. A reasonable winter outing with care on the heathery descent.

Around Arkleton Hill on the SCOT network
Getting there, basing yourself, and what to do off the hill.
Before you go
Hillwalking carries real risk and the responsibility for any day on the hill is yours. Conditions in Scotland change fast and can differ sharply from the forecast — check the weather and the ground before you commit, turn back when the day stops working, and carry map and compass with the ability to use them rather than relying on a phone.
Mountain forecasts: MWIS and the Met Office mountain forecast. Access rights and responsibilities are set out in the Scottish Outdoor Access Code.
We check what we publish, but we cannot check the route on the day you walk it. Nothing here is a substitute for your own judgement.
