Castletown is a village 6 miles east of Thurso bordering the coastline and Dunnet Bay. The village is short walk to the outstanding sandy beach at Dunnet where you have two miles of pristine beach, a caravan and camping site, along with Dunnet community forest with its lovely nature filled walks.
At Castletown there is a tidal harbour that is used by local people for leisure, and a few commercial crab and lobster fishing boats. The harbour was originally built to support the export of flagstones made locally by the Castlehill Pavement Works that was started around 1824 by James Traill. Evidence of this industry is still found around Castletown with a dedicated flagstone heritage trail near the harbour. This heritage trail is part of the Castletown Heritage Centre that has recorded a fascinating record of live in Caithness in historical and more recent times.
