Nestled within White Tank Campground lies a fun and short walk to Joshua Tree National Park's natural arch. The arch spans about 30 feet in length and is viewable directly from the trail, but the fun lies in the open space of rocks that you can explore off of the trail. The texture of the rocks is like a gritty sandpaper, which makes walking and climbing on them really easy. These rocks get their shape and texture from weathering that results from moisture being trapped on the rock surface long enough for certain minerals to begin dissolving. Running water and wind then act as agents to wash the sand away. The environment here has been shaping and changing for millions of years. Explore the surroundings at night for an entirely different experience and with no crowds.
