1. Trail Difficulty

The trails on Mount Diablo vary in difficulty, from beginner-friendly fire roads to expert-level singletrack. Some of the most popular intermediate trails include the Wall Point Trail, which offers stunning views of the San Francisco Bay, and the Eagle Peak Trail, which features a challenging climb followed by a technical descent through steep switchbacks. Expert riders will enjoy the Back Canyon and Oyster Point trails, which offer steep drops and rocky terrain.

It’s important to note that many of the trails on Mount Diablo are not for the faint of heart. Riders should come prepared with the appropriate gear and experience before attempting the more advanced trails. Additionally, it’s recommended to ride with a group or partner for safety reasons.

2. Trail Access and Parking

There is a parking fee of $10 per vehicle, and parking can fill up quickly on weekends and holidays. Visitors can also park at the Mitchell Canyon Visitor Center for access to several popular trails, including the Mitchell Canyon Trailhead, which leads to the summit.

Riders can also access the trails from the South Gate entrance, located near Danville, but parking is limited and there is no direct access to the summit from this entrance. Most of the mountain bike trails are located on the north side of the mountain, so the North Gate entrance is the most convenient option for riders.

Riders should bring plenty of water and sunscreen, and consider riding earlier in the day or later in the evening to avoid the heat. During the winter months, the trails can be muddy and slick, so riders should check trail conditions before setting out.

It’s also important to note that the park occasionally closes due to fire danger, especially during late summer and early fall when dry conditions are prevalent. Riders should check the park website for the latest closure information before heading out.
