Loch Stemster is a beautiful small loch next to the Achavanich Standing Stones, just off the A9 road at Achavanich. It is also the start point for the 3-mile walk into the Munsary Peatlands Nature Reserve owned by Plantlife, an important natural bog area that is part of the Caithness Flow Country. This nature reserve covers 1,238 hectares (3,058 acres) and is a Site of Special Scientific Interest (SSSI) designation.
The walk along the farm track can get muddy and suitable footwear should be worn, along with warm and waterproof clothing (or at least taken with you) even in summer, as conditions can change quickly over the moorland. You can get a downloadable leaflet in pdf format from Plantlife on the Munsary Peatlands walk.
Loch Stemster and the area around it is a working farm and you may come across cattle roaming freely, along with sheep. Dogs need to be kept on a lead near any farm or wild animals (deer). A small parking area at the loch is available, free of charge. Fishing is available on the loch, permits are required and can be obtained from Hugo Ross in Wick.
