Overview:
Quicksilver Mockingbird Loop - Hacienda - Randol - New Almaden is about 3.7 miles long and located near English Town, California. The trail is great for hiking and normally takes 1-3 hours.
The upper part of the the Day Tunnel trail is washed out with lots of exposed rock, but it's passable. Once back on the New Almaden trail, the vegetation becomes lush with ferns and good flow of water in the two creeks that are crossed.
