From the Highmoor Reserve car park head North West towards a gate and turn right at the sign. After 250m going downhill cross the stream over the wooden bridge and after another 250m on after the stream crossing take the path to the left (the right leads to the small Kamloops Dam wall).
In front of you is the Salma Dam and just before the stream follow the path left (you go right and cross the stream for Caracal Cave and Fulton's Rock) so the Salma Dam will now be on your right.
Follow the path which winds left and right gently uphill till you reach the highest point, which is rewared with stunning view of Giant's Castle. Return via the same path.
