Altnabreac (from Scottish GaelicAllt nam Breac) is a tiny settlement within the former county of Caithness, in the north of Scotland, and now within the Highlandcouncil area. The settlement, notable for its remoteness, consists of Altnabreac railway station and the former Altnabreac School which had one teacher/head teacher (David L. Jenkinson). The school classroom was closed and converted from a school/house solely into a house in 1987. The former gamekeeper's house sits adjacent to the school and station. There is a natural spring about 200 yards from the school providing crystal clear drinking water. During the 1980s peat banks were worked to provide fuel for the residents who regularly used to be cut off from the nearest town of Thurso during the winter. It can only be approached by train by special request to stop at the unmanned station, or along unsurfaced Forestry Commission roads from the nearest village, Westerdale, about 12 miles away.
Altnabreac, like Dounreay, was considered as a location for a final repository for the UK's nuclear waste. However, this idea was not pursued.
