If you make the summit a fantastic view awaits. Be aware the road goes down then up to the road about then up again to the summit!…

Climbing Mount Umunhum is a tough but rewarding challenge. The road is steep, with sections reaching up to 18% grades, so pace yourself. The views from the top are spectacular, making the hard work worth it. Start early to avoid traffic and the heat, and be prepared for a long, demanding ascent.

The Mount Umunhum Trailhead offers some amenities, including bathrooms at both the start and summit. With parking available for about 20 cars, this trail provides great views and is a great spot for sunsets. Aim to hike early in the morning or in the evening as it can get very hot in the summer.

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.

A fast and fun trail that predominantly runs through the trees. It can be ridden in both directions and is not overly technical.
