The hill immediately above Hethpool is Great Hetha. This is an easy walk from Hethpool house, maybe 1 hour or less to the top. You get great views for very little effort and there is an iron age hill fort on the top. There is a path down the opposite side towards Trowupburn and from there you can follow the road through the Elsdonburn valley back to Hethpool.
View from the top looking towards Hethpool and northwards out of the Valley
The old fort on the top. Now just a ring of stones
If you take the track down towards Elsdonburn then you want to head for the small copse of trees beside an old quarry
