For the energetic, the Long Walk, which follows Howick Burn all the way down to the sea for about 1½ miles, is another adventure; it is a long valley and part of the new arboretum. It has been mapped and the plants will be labelled. Quite a few new paths and footbridges have been made.
The Arboretum covers about 65 acres of woodland walks with over 11,000 trees and shrubs planted from 1988, mostly labelled. The East Arboretum is not suitable for wheelchairs.
