Rocks Bungee Adventures based in San Francisco and Sacramento is an extreme form of bungy jumping and offers big jumps off overhanging granite cliffs. First the adventure involves a hike to the top of the cliff, then a rappel down to the ledge just above the overhang, and then you jump off the ledge maintaining good clearance of the rocks and parallel to the wall. It's not over yet, now you have to climb back up a rope using rock climbing ascenders, it's an extreme adventure. Here there are two types of jumps as well, there's the bungee jumps using elastic rubber and there's the rope swings using nylon climbing rope, vastly different with interesting possibilities, so come for the world class challenge.READ MORE
