When the cinnabar (mercury ore) mines at Quicksilver Park were active in the late 19th and early 20th centuries, English Camp housed around 1,000 residents, primarily consisting of Cornish miners and their families. Today, only a few remnants of structures remain. There are some lovely picnic tables here, making it an ideal spot to stop for lunch and take some memorable photos.

At the summit of Mt Umunhum is an 8 story tower that was used as a radar outpost by the US Air Force until 1980. In addition to this piece of military history you'll also find stunning views in all directions. On clear days you can see as far as San Francisco and Monterey.

This stretch of double track fire road is more challenging than it might appear. For starters there are plenty of tight turns to keep an eye out for, plus at least one prolonged section with a 20% grade. It pairs nicely with the Woods Trail.
