Strath Halladale is one of the emptiest valleys in mainland Britain, and East Halladale is a scatter of crofts and sheep fields along it. The A897 runs up the strath from Helmsdale on the east coast to Melvich on the north coast, following the Halladale River for much of the way, and for long stretches you will see more deer than cars. It is single track with passing places, so the rules are simple: pull in to let faster traffic by, wave, and never park in a passing place.
All around lies the Flow Country, a vast rolling blanket bog that UNESCO added to its World Heritage list in 2024. From the saddle it can look like nothing much, a brown and olive moorland broken by pools that shine silver under the clouds. In fact it is the largest expanse of blanket bog in Europe, peat built up over thousands of years, locking away enormous amounts of carbon. In summer the pools ring with the calls of greenshank, golden plover and dunlin, and divers nest on the lochans. At Forsinard, a little way south, the RSPB runs a visitor centre in the old station on the Far North Line, with a boardwalk out onto the bog that is worth half an hour.
The river is a famous salmon water, and the strath carries the memory of the Clearances, when nineteenth-century landlords pushed families off the land for sheep. The ruins of old townships are still visible if you know to look for them.
The road itself is a joy if you take it on its own terms. The surface is mostly decent but patched, with cattle grids, sheep that wander without warning and occasional loose gravel on the bends. Weather comes in fast off the Atlantic and the Pentland Firth, and a dry morning can turn into horizontal rain by lunch. Long June evenings give you light almost until midnight; midges in July and August are a real nuisance whenever you stop and the wind drops.
Plan fuel carefully. There is nothing reliable in the strath itself, and the nearest town of any size is Thurso, about thirty kilometres away, with Helmsdale and the north coast villages as the other options. Carry water, snacks and a warm layer, and enjoy a silence that is hard to find anywhere else in Britain.
