January 7, 2024, Tassajara Ridge Trail

The Tassajara Ridge Trail is a beautiful ride with rolling hills and overlooks boasting excellent views of San Ramon, Dublin, and Danville. Taking this route clockwise will give you longer, more gradual downhill sections and shorter and steeper climbs. The trail is at its best during the spring and early summer when the hills are lush green, wildflowers are blooming, and cows can be spotted grazing nearby.

January 3, 2024, Wall Pt. Road

Wall Point Rd is one of the best fire roads for riding in the area. It has excellent views of Mt Diablo, Las Trampas, San Francisco, Mount Tamalpais, and the Sacramento River delta in the distance. While quite climbable, it is much more fun to descend. There are some blind corners, steep rocky sections, and off-camber sharp turns with short climbs interspersed to slow you down. This route is popular for hikers, so try to keep your speed under control during this fun ride. The trail is entirely exposed to the afternoon sun, so getting an early start is recommended.
