Estimated Times to Run







Head through the gate and follow the clear 4WD track for about 800m, where it crosses a gravelled turn-around area and enters the single track.

After another couple of hundred metres you reach the intersection where you have the choice about which way to go... you do both, so it's up to you, however we suggest you go right first... this takes you to Humphries Dam. This is the less impressive of the two you will visit (hence the suggestion to do this first). The dam comes on you quite suddenly after about 1.7km from the intersection and is not extremely impressive although the lake is very serene.

Once you have finished there, retrace your steps to the intersection and head out to Barnes Dam, this is by far the more interesting trail with more river highlights, a short tunnel, bridges and an impressive dam that you can climb the steps to the top of (you can't go further though). Also the waterfall caused by the outlet of the dam is very cool.

Once you have you fill, head back to the start.

Historic water pipes and dams, one of which is still used as back-up water for Picton.

This trail should be pretty good all year round, it's very well built.

There are some steep fall-offs to the side of the trail, not much danger to runners but something to be careful of.

Really nice gentle gradient to each of the dams with plenty of shade to make this a great outing on a blistering hot summer's day. Thanks for sharing Mike.
