Claish Moss Nature Reserve

See one of Britain’s best examples of a raised bog. Claish Moss has evolved over the last 8,000 years.

A network of pools speckles the bog’s dome-shaped surface. Deep below, pollen grains that survive in the peat are a record of the area’s plant life since the bog first began to form.

Claish Moss is protected as a Site of Special Scientific Interest, a Special Area of Conservation (which extends across Kentra Moss) and a Ramsar site.

Scottish Natural Heritage owns and manages the reserve.

Best time to visit

June to September, to see wild flowers in bloom and spot breeding birds.


The reserve has no formal paths. Deep pools on the bog surface make it dangerous to walk on.
