Chinaman's Gully was named for the many Chinese who worked for the mines. Is a designated wildlife corridor at this point. You can access the reserve around the side of the locked gate. If you wish, follow the track about 130m into the reserve and up the hill a little to where you can see the edge of the gorge to the right of the track. Take a camera with you and look over the edge there for a spectacular view of the creek cascading into the gorge (the creek is running at the time of publishing) in an almost completely hidden fold of the hillside. Well worth the walk, but not recommended for the fainthearted or the foolhardy.
The road is very narrow through Chinaman's Gully. If you have a 4x4 you can get completely off the road at GZ (preferred if you plan to walk into the reserve). However, if you drive a small car like I do, there is a spot up the hill to the North just wide enough to pull over and then walk back down to the cache. I have added a Parking waypoint for that spot, but don't leave your car there longer than absolutely necessary.
The cache is a micro in a camo container.
Caution: If the creek is flowing strongly after heavy rain DO NOT CROSS IT or you will end up washed into the gorge. If you are here under those conditions you must go the long way around to get the rest of the caches in the trail.
