Cairns are the earth or stone mounds that can form part of a range of different burial monuments, including long barrows, round barrows, and portal dolmens — as at Dyffryn Ardudwy.
Tips for visiting cairns:
- You should not walk on the cairn, as it could be dangerous and cause damage to the site.
- Cairns can sometimes be very difficult to spot, as they can be little more to the naked eye than a small area of ground on which heather does not grow.
Tips for photographing:
- Due to the large amount of stones on a cairn site, these can be very difficult to photograph.
- You should walk around the outside of the cairn taking photographs at eye-level.
- You should then circle the cairn again taking photographs from lower down and higher up to cover different angles.
