The loop starts on the Homestead Trail, which transitions into the Old Homestead Loop. The only navigation that needs to be done from there is to stay on the loop until returning to the Homestead Trail.

You will explore the hills of Black Diamond Mines Regional Preserve while traversing this meandering trail.

This area is at its most beautiful during the spring when the grass is green, and a variety of wildflowers pepper the hillside. Of course, Old Homestead Loop is popular year-round for its gorgeous views and ease of access.

This is a busy trail on the weekends—expect to encounter other hikers along with cyclists, cows, and horseback riders. You may need to park just outside the Contra Loma Regional Park gates if parking at the trailhead is full.
