Talla and Megget Reservoir Road — Tweedsmuir Hills Circuit via the Southern Upland Divide
Drowned valleys and high moorland in the Southern Uplands.
The back track connecting Talla Reservoir to Megget Reservoir through the Tweedsmuir Hills in the Scottish Borders is the kind of road that appears on OS maps as a thin dotted line and delivers exactly what that promises. Starting off the B712 near Tweedsmuir village, the track climbs above Talla Linns waterfall — a legitimate drop worth stepping out for — before crossing the high moorland divide at around 1,700 feet and descending to the Megget Reservoir dam wall. The surface is deteriorating estate track; expect deep ruts after rain, exposed bedrock on the crest, and a handful of gates. St. Mary’s Loch and the Tibbie Shiels Inn sit at the end of the Megget arm and provide a legendary excuse to stop.
Moderate to difficult depending on season — autumn rain turns the upper section greasy and the descent to Megget holds water badly after prolonged wet spells. A high-clearance 4WD with decent all-terrain tyres handles it without drama in dry conditions; mud-terrain rubber earns its keep in October. No permit required but Talla Estate manages the upper section — keep gates closed and don’t push through if the track is visibly deteriorating under your wheels. Nearest fuel is Moffat or Peebles. No cell service across the plateau. Bring lunch; the scenery on the Megget side looking south toward the Ettrick hills is genuinely outstanding.

Frequently asked questions
Can a stock Defender 90 or Hilux handle this without a lift?
A stock high-clearance 4WD is the minimum — unmodified Defenders, Hilux, and Land Cruisers handle it fine. A lifted crossover or soft-roader will struggle on the rocky sections near the divide and the boggy moorland tracks.
When is this circuit actually passable — snow cuts off the high sections fast up here?
May through September is your window. The high moorland track near the Southern Upland Divide holds snow and ice well into spring and can become waterlogged and impassable after heavy autumn rain. Don't gamble on October or April without local intel.
Do you need a permit or permission to drive the Talla and Megget estate tracks?
Scotland's Land Reform Act gives broad access rights, but vehicular access on private estate tracks is not covered — you'll need to confirm access with Talla Estate and Scottish Borders Council before you drive. Turning up unannounced and assuming it's open is how these tracks get locked.
What's the hardest section and what makes it technical?
The roughest stretch is the high moorland track crossing the Southern Upland Divide, where the surface turns to loose rock and deep ruts with no recovery room on exposed ground. The water crossings at Talla Water are unbridged and depth can vary significantly after rain — probe them on foot first.
There's no cell service out here — where's the nearest fuel and is there anywhere to camp legally?
Fill up in Peebles or Moffat before you go — Tweedsmuir village has nothing. Wild camping on foot is protected under Scottish law, but vehicular wild camping in the Borders is a grey area; your best bet is to plan to exit the same day or pre-arrange with the estate.
