Two impressive Neolithic cairns dating from 5000 years ago.
The Grey Cairns of Camster are quite well hidden so you need to intend to visit them to come across them. However, after a 5 mile drive down an unclassified road, there is off-road parking, information boards and boardwalks. It is free to enter and open all the time.
Follow the boardwalks and explore the cairns at your leisure.
Notes for visitors with limited mobility:
There is a car park here and broadwalks to the cairns but, although even and level, these are possibly too narrow to be accessible by wheelchair.
