This trail starts at the Clark Road Trailhead at the very north part of Wildcat Canyon Regional Park. There is limited parking at the trailhead so arrive early if you plan on hiking or mountain biking on the weekends. The first half mile or so requires that dogs be on leash. Once you enter Wildcat Canyon, dogs can be off-leash on the trail. This loop offers gorgeous views of the bay including Mount Tam in Marin and San Pablo Reservoir in the east bay. The trail gets hot during the summer months so bring plenty of water. There is a lot of wildlife out on the trail including hawks, coyotes and foxes. Keep an eye out for cows as they are often roaming in the fields.

Back part of loop not maintained with trail sign actually reading dead end.. Extremely windy in sections. Our staff meme day and cold and cloudy but I could imagine stunning views. Ground extremely hard.

This is a fun loop with some good incline and fantastic views, however the last part of the loop is unmaintained during the summer months. Today it was extremely overgrown and lots of ticks. If you have a long haired dog I recommend staying on the wider trails. Great trail for mountain biking and trail running.
