Havey Canyon Loop Trail is a 8.2 mile lightly trafficked loop trail located near Kensington, CA that features a lake and is rated as difficult. The trail is primarily used for hiking and trail running and is accessible year-round.
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.
