Johnson Valley is home to some of the most extreme and exciting off-roading routes in all of California known as the Hammers. Claw Hammer is the shortest and "easiest" of the three main Hammer trails but still provides plenty of extreme rock crawling challenge. Claw Hammer features huge boulders, tall ledges, tricky waterfalls, and tight spots where body damage is likely. Only experienced drivers and spotters operating modified vehicles with armor and sliders should attempt. Also, do not set out alone as vehicle damage and failure is possible.
