With only six campsites, Junction Campground is Mount Diablo State Park’s coziest. Located at the junction between South Gate, North Gate, and Summit Roads, the campground sits under the shade of coast live oaks and opens to west-facing views that overlook Diablo’s lowers slopes and Diablo Valley. Each campsite comes equipped with traditional Diablo stone grills.

The Junction Ranger Station sits near the entrance road to the campground where helpful park and recreation information can be found. The Summit Trail also passes nearby, connecting campers to nice hiking and biking options around Mount Diablo’s hillsides and notable landmarks.

Dogs are permitted at the campground, but they must remain on a 6-foot leash, and they are not permitted on the nearby trails.
