Kovar Trail to Mt. Diablo-Briones Trail via Ridge Top Trail
- Covering 4.5 miles of terrain, this moderately difficult trail has some rugged patches as well as a number of easy stretches. The incline in most places is mild, though the last portion of the trail is steep, and those who would prefer to avoid the climb can veer off on one of the adjoining pathways. The trailhead can be accessed by going through Howe Homestead Park, just off of Walnut Boulevard in Walnut Creek. Scenic views of Mount Diablo, the valley and Shell Ridge reward hikers for their efforts year-round, though the most colorful times to hit this trail are during spring and fall. There is no entrance fee and free parking is available at the trailhead.
Iron Horse Regional Trail
- The Iron Horse Regional Trail is a multiuse trail connecting 12 different cities. It follows the abandoned Southern Pacific Railroad right-of-way and covers 55 miles through Concord, Pleasant Hill, Walnut Creek, Alamo, Danville, San Ramon and ending in Dublin. The trail connects rural, residential and commercial areas, though those hoping for natural scenery will not be disappointed, as the trail provides a view of Mount Diablo and glimpses of the valley. Walnut Creek is roughly the midpoint of this trail, and people can join the trail at this point through Heather Farm Park. Cyclists, hikers and equestrians are all welcome, but motorized vehicles are not allowed on this popular trail.
- Shell Ridge Open Space
- Shell Ridge has trails for biking, hiking and horseback riding through woodlands and grasslands. Set at the base of Mount Diablo, Shell Ridge spans approximately 31 miles. Mountain bikes are allowed on the paved sections. One of the most popular routes begins at Hanna Lane and runs in a 3-mile loop through Shell Ridge and the Ridge Top Trail. Parking and access are free. Within the Shell Ridge Open Space is the Borges Ranch. The Ranch, built in 1901, is on the National Registry of Historic Places and currently serves as a ranger station, residence and maintenance facility. Free weekend tours are available should you want an educational break in your hike.
Mount Diablo’s Grand Loop
- Mount Diablo’s Grand Loop is a moderately strenuous 6.2-mile hike with a trail that encircles one of the Bay Area’s highest peaks. Hikers can access the trailhead by parking in the wide turnout of Diablo Valley Overlook and joining the Juniper Trail, which begins from the picnic area. Most of the hike is on flat, fire-road trails, but there are points that are steeper, narrower climbs. From the top of Mount Diablo, visitors can see a sweeping panorama of sites, including the San Francisco skyline, the Farallon Islands, the High Sierra and the Central Valley. You can also take advantage of the museum at the summit, which highlights the cultural and natural history of Mount Diablo State Park. For those who would like to engage in a shorter version of this hike, there is a roadway to the summit that can allow people to customize the length of their trip while still seeing some amazing views. There is a per-car fee to enter Mount Diablo State Park.
