The Grey Cairns of Camster are extraordinary, not just because of their level of preservation and age, but also because they are relatively unknown. Situated in the north of the Highlands in the county of Caithness, these fascinating structures were built around 5000 years ago – some of the oldest in Scotland. The longer cairn is an astonishing sixty metres (200 feet) feet long! Visitors can even crawl inside, although it is wise to keep heads low as the tunnel is quite small. Inside the chambers there are recently installed skylight windows, allowing light to enter. The sensation of being inside the tomb is an odd one (and not for those with claustrophobia), but worth the crawl.
