We climbed the equivalent of 24 floors and 6,000 steps but it wasn’t strenuous. If adventuresome, you can climb rocks of all sizes. We mostly stayed on the path. Darrel of Desert Tours was our guide and he is very knowledgeable. Wear good shoes for the approximate one mile hike. Plenty of picnic tables there for eating. Visitor center for Joshua Tree is in town if seeking a souvenir.
