Machrie Moor Standing Stones is a cool spot on the west side of Arran where you can check out some ancient Neolithic vibes. Think stone circles, standing stones, burial cairns, and hut circles all hanging out on a moorland dating back to 3500-1500 BC. It's like a time capsule of religious rituals and domestic life from over 4,500 years ago. Open year-round for your historical exploration needs!
