Join us on a hike through two old, abandoned mining towns (Sommersville and Stewartville). Back in the mid-1800s to the early 1900s the Black Diamond mining towns were the most productive coal mines in the state of California and supported the construction of San Francisco, Stockton, and Sacramento. We will be able to tour an old sand mine, hike up a trail that was once used by miners to travel between Sommersville and Stewartville, visit Rose Hill Cemetery and enjoy great paneramic views of Mt Diablo and the Sacramento Delta.

Total elevation gain is approximately 1800 ft and the hike is about 7.5 miles (4-mile option available).

We will be stopping for lunch at Stewartville Campground for a lunch break. It may be warm on the day of the hike so please bring a 2 liter water pack and something to eat for lunch.

Facilities: There are bathrooms, water, and picnic tables available at the trailhead and one restroom in the Stewartville Campground.

Parking fee $5.

Dogs are NOT allowed on my hikes due to safety concerns for the hikers and dogs.
