“Some fun descents and one brutal climb in this loop through a once-thriving mining district.”— Bob Gardner

Nice views in all directions, with Rose Hill Cemetery in the distance looking west with Sand Creek Valley to the east and Mount Diablo to the south. Head left and UP the Ridge Trail. It's steep but short and the top is the high point of the ride.
Continue east as you mostly descend on a roller-coaster, ridge-top fire road. Views open up over the towns of Antioch and Brentwood out to the Sacramento Delta. One last twisty downhill brings you back to the Stewartville Trail.
A sharp right and you'll be heading south then west on this fast graveled section. Several trails branch off to old mining sites but are mostly dead-end trails. After passing a large corral, the Stewartville town site is reached. Nothing left but mine tailings. The road makes a sharp right at a boundary fence and begins the steep climb to the ridge. A couple switchbacks ease the grade but stopping to enjoy the view is advised. First to the top gets a choice spot on the rest bench.
It may be tempting to head straight down Stewartville Trail to the parking lot but the last loop offers more views and another fun descent. The Carbondale Trail starts with a short climb followed by a gradual descent to the River View Trail. Both trails offer great views over the Delta and the River View Trail is a fast and smooth descent, just watch for hikers and horses.
