Lost Goldmine is a mostly blue trail with some difficult ups/downs through arroyos. There are no man-made features, so enjoy the natural ones, including excellent up-close views of the Superstition Mountains.
This is a heavily-used hiking and equestrian trail, so show respect to other user groups and there will be no problems. As always, close all gates you pass through.
Access via parking lot at the east end of Cloudview Rd. in Gold Canyon - follow the "hiker" symbol signs. There is plenty of parking, but no water or toilets.
