Enjoy hiking? About a quarter mile west of the entrance to Jumbo Rocks campground, on the south side of Park Blvd., there are several large rocks blocking the entrance into what looks like an old jeep road that heads off into the desert. What more of an invitation do you need? There’s plenty of room to park nearby, so pull over, take a day pack with plenty of water and some snacks, and hit the trail. Plan on about four miles roundtrip, roughly 50 feet of elevation change and a wonderful time.
