After a short drive past the dam and just after crossing a bridge, you will come to a dirt road on your right hand side. You can either park at the top, or drive down to the middle where the camping spot is. Continue on food down the rest of the dirt road until you've reached the water. This is the area known as the docks. This area will give you a neat view of the backside of the dam as well as Mount Begbie. If you follow to the left, you will notice a small trail leading in to the bush. This trail comes out at a little secluded beach, and the right path to the geo cache.
The cache itself is a medium official geo cache bison tube, placed off the ground.
