Forse Castle is a little-visited 14th-century ruin on the Caithness coast between Whaligoe and Lybster, sitting on a clifftop above a dramatic geo (narrow cliff inlet) that acts as a natural moat. The castle was a Sutherland stronghold and the ruins retain some walling. The surrounding area has other points of interest including the Latheron Wheel, a carved Norse cross. This is deep Caithness โ rarely visited even by NC500 travellers who rush through this stretch โ and its isolation is part of its appeal.
On the A9 between Lybster and Latheron. Turn off at Forse farm track. The castle is a short walk across the fields to the clifftop.
