Fodor's Expert Review Grey Cairns of Camster

The remarkable Grey Cairns of Camster, two Neolithic chambers made of rough stones, were built more than 5,000 years ago and are among the best preserved in Britain. Camster Round Cairn is 20 yards in diameter and 13 yards high, while Camster Long Cairn stretches an extraordinary 77 yards. Some 19th-century excavations revealed skeletons, pottery, and flint tools in the round cairn's internal chamber. They are in an isolated location, around 8 miles southwest of Wick and without a visitor center in sight, so if you feel adventurous and don't mind dirty knees, you can crawl into the chambers (the metal grills over the entrances mean they appear locked, but they aren't). To get here, you'll need to drive 5 miles along the unnamed road from Occumster to Watten; when you're just beyond Lybster on the A99, look out for the brown signposts pointing the way.
