The Joshua Tree National Park Superintendent's Compendium states that: 1. Vegetation is not allowed to be used as an anchor. 2. Only neutral or rock colored bolt hangers are allowed.
The Central Wonderland lies just past Wonderland Valley and is a good spot (with a few exceptions) to escape the crowds that are found at the Astro Domes and Lenticular Dome.
Standard Wonderland approach past the Freak Brothers Dome after which Disneyland Dome and Thrutcher Dome will come into view on your right - you have arrived! Consult the individual crags for more detailed approach information. Plan on a 30 - 45 minute hike from the trailhead.
