Belas Knapp is an neolithic long barrow burial mound found on the side of Cleeve Hill a few miles out of Cheltenham, overlooking the town of Winchcombe.
You reach it by car via Corndean Lane or by hiking up the Cotswold Way from Winchcombe. It's a 10-15 minute climb up the steep hill to the site.
You can go into the burial chambers and the site is supposed to be situated on a ley line. It's well worth the climb to visit, be sure to wear proper footwear since the path is not paved.
