Great hike through EBMUD watershed, a beautiful display of wildflowers on the east side of the trail. Not a lot of shade, lots of cows and beautiful views of the lake. A quick walk to the top of John Bull Peak Spur Trail is a must! There's a picnic bench at the top with a 360 view where you can see Mt. Diablo in the west and the snow-capped sierras in the east. Please note a permit is required to use this trail.

The description of the loop is deceiving. There is no signage in the parking lot says you need to hike at least 4 miles before the loop trailhead. The trail that starts at the parking lot is part of the Coast to Coast Trail. The trail is actually the size of a small road..well maintained. Moderate walk, with the exception of the hill as you go towards the parking lot. Did not seem so steep on the way in!

More of a walk than hike but the view at the top is well worth the time spent. Don’t miss the Olive orchard off the coast to crest trail while you’re there.

It's just a gravel road for horses. You need a permit and they don't issue it at the "trailhead". There is also no lake access.
