What to expect on Pfeiffer Park – Mine Hill Trailhead loop from Branham
This route takes you through the scenic Almaden Quicksilver County Park, primarily on the Mine Hill Trail, which is a 100% doubletrack dirt and gravel road.

The scenery shifts between substantial tree cover, including oak and redwood woodlands, and open meadows. Keep an eye out for historical mining sites, such as the visible San Cristobal Mine entrance and structures at English Camp, adding a unique historical layer to your ride. Expect an uninterrupted climb of approximately 1,100 feet over the first three miles, with an average grade of 8.5% on parts of the Mine Hill Trail, so be prepared for sustained effort.
Planning your visit
The Almaden Quicksilver County Park offers multiple entrances, with the Hacienda entrance being a popular starting point for bikers due to its convenient access to a wide range of bike-legal trails. While the specific "Pfeiffer Park" starting point might refer to a local connection, the broader park network is well-established. The route is accessible from urban areas, including connections near Westfield Oakridge. Given the significant climbs, ensure you bring plenty of water, especially on warmer days. Early spring is an excellent time to visit to enjoy abundant wildflowers.
