This is the watershed between the Annan and Tweed systems and it lies in the administrative region called Dumfries and Galloway.
The regional boundary runs erratically eastward from Annanhead, then goes north around Loch Skeen (or Skene) before heading south east to Birkhill Cottage in Moffatdale where the pioneering geologist Charles Lapworth stayed from 1872 to 1877.
[4] The north facing side of the Moffat Hills is bounded by a minor road (no road number on the Ordnance Survey map) which runs from Tweedsmuir village to St Mary's Loch, passing along the banks of the Talla Reservoir and the Megget Reservoir and rising to 450 metres by the Megget Stone.
Where these two lochs almost join there is a monument to James Hogg[11] the Ettrick Shepherd, visit Tibbie Shiels Inn[12] and then follow the Moffat Water down Moffatdale past the Grey Mare's Tail waterfall.
There is a project in progress to restore a wild woodland environment, as it would have been six thousand years ago, to the treeless Carrifran Glen.
Once the Yarrow and the Ettrick Waters join they in turn lose their identity when they meet the River Tweed between Selkirk and Galashiels.
The Annandale Way[16] is a new 55 mile (85 km) long-distance walking route which follows the valley of the river Annan from its source to the sea.
In the Southern Uplands of Scotland there are plenty of wild places in which to exercise this right, of which The Moffat Hills range is amongst the best.
[20] The Blackhope Burn joins Moffat Water close to a farm called Capplegill (OS.
Just to the north east of Capplegill (roughly 150 metres) there is room for a car or two to park by Blackshope house.
From there descend to the water course in Whirly Gill before climbing to the top of Saddle Craigs at the head of the Blackhope Glen and just below Hartfell Rig (739 metres).
Around the waterfalls offers the best views and also some quite interesting terrain to scramble over - not only around the waterfalls themselves but also while crossing the face of the steep lower slopes of Firthhope Rig on the way up to Games Castle (a natural feature resembling a castle) and Rotten Bottom (the sump area for all the peat hags round about).
There is a visitor centre by the car park where it is possible to "watch live" wild birds nesting - as viewed from a remote camera on the hillside.
Loch Skeen has also been used successfully[22] to try to preserve the endangered species of fish called the vendace[23] which has a history in Britain going back to glacial times.
The classic route here is to park at Annanhead above the Devil's Beef Tub (room for several vehicles there) and walk up over Annanhead Hill, Great Hill and Chalk Rig Edge to Whitehope Heights, a route which goes round the top of the Beef Tub.
The area in the valley around Ericstane is rich in ancient remains (settlements and burnt mounds) and before you get back to where the car is parked you will pass a monument[26] above the Beef Tub to John Hunter of Tweedsmuir, a covenanter who was shot in 1685 while trying to escape from dragoons by climbing the side of the Beef Tub.
NT075103) proceed northwards on the A701 heading out of Moffat town centre till you arrive at a mini roundabout by the school.
They aim to return lost wildlife and habitats to Corehead and to conserve the unique character of the Devil's Beef Tub.
From the burn climb to Swatte Fell, go on to Hartfell and come down over Arthur's Seat making for the gully above the spa.
NT152203) is by a cattle grid at the highest point between the Talla and Megget reservoirs on the minor road which runs from Tweedsmuir on the A701 to Cappercleuch by shore of St Mary's Loch.
This walk can be lengthened slightly by taking in Dead For Cauld which offers fine views over the Megget reservoir.
