Wow, superseded my expectations! We missed the trail we had planned so took a longer one - Wildcat Canyon, Belgum, Nimitz, Curran, Wildcat George, Curran, slight deviation to Lake Anza, back to Wildcat George, and took Lone Oak back to Wildcat Canyon. It was a 15 mile loop with few hills and beautiful with creeks, reservoir, views of East Bay, cows, and wild turkeys. Best trails of them all were Curran and Wildcat George. Not crowded with many parking lots. Cell phone also works the entire time :). I would return and explore many other routes.
Spectacular views of the San Francisco Bay and San Pablo Reservoir. Lots of wildlife - coyotes, turkeys, cows. Ran the loop after it rained so pretty muddy but trails are very maintained and easy to navigate. Definitely some good inclines but the views are worth it and always fun to watch the cows. Make sure the cattle gates lock when you walk through. Also be mindful as you cross a couple of streams. Parking fills up fast on weekends.
A nice trail that I did with 4 friends. It goes in and out of trees and mostly wide open spaces with some pretty good views. Most of the trail is old roads with a small mix of single track connectors. We were there at the wrong time watching a couple of bulls going at each other until one decided to chase us..... Fortunately there are some huge power lines there and we were close and jumped up on the cement supports and got out of harms way.
I started at the Alvarado Park and went for few miles strenuous uphill hike: First to the Bonitas Gate Trail, then the Monte Cresta Trail, I passed the Belgum Trail and reached the San Pablo Ridge Trail. Instead of hiking up to the ridge I went below it. Coming down the hill by the Mezue Trail and turned right onto the Wildcat Creek Trail and back to the parking lot. Total distance was 6.5 miles with 1,263 ft. elevation (see my recorded track). This track was rated moderate and I did it for little over 2 hours. This track has many great views for the hills, canyon and the bay (see photos). I highly recommended.
