This is a great area for bouldering, climbing but also hiking in Joshua Tree. From the Barker Dam parking lot, there is a trail that goes East for a bit and will lead you to the remains of a pink house. Opposite the pink house is the entrance to the Wonderland of Rocks, making your way North into the boulders. We just did a 2 miles out and back hike, very fun, tons of prickly pear cacti!
