Machrie Moor Stone Circle
Lonely Planet review
On the western side of the Isle of Arran is the Machrie Moor Stone Circle, a pleasant 20 to 30 minute stroll from the parking area on the coastal road. There are actually several separate groups of stones of varying sizes, erected around 4000 years ago.
It's an eerie place, and these are the most impressive of the six stone circles on the island. There's another group at nearby Auchagallon, surrounding a Bronze Age burial cairn.
