A Beautiful Spring Hike

Apr 20, 2023 06:34AM ● By Mary Nagle Save Mount Diablo

Looking for a new adventure? Trek through the rolling hills of Black Diamond Preserve on Lougher Loop. This loop is great for running, dog walking, looking for spring flowers, and mountain biking. California poppies, Ithuriel's spear, and Sacramento Valley buttercup are among the wildflowers you will see on the rolling green hills of this easy-to-navigate trail.

Trailhead location: Somersville Road, across the road from Sidney Flat

Practically on the border of Pittsburg and Antioch, this scenic hike is a great one to add to your spring plans. Once you’re on this trail, it’s easy to navigate. Just stay on the Lougher Loop trail for the duration of the hike and you’ll end up back where you started. Besides a rainbow of wildflowers, the route offers unobstructed views of Black Diamond’s historic Railroad Bed trail and gorgeous oak savannas.
