Jumbo Rock Campground, Joshua Tree National Park, CA
Our first camp was Jumbo Rock Campground in Joshua Tree National Park. Reservations are on a first come basis and it's packed on weekends in the spring and fall so we arrived before noon on a weekday to get a great spot for the entire week.
NOTE - There water and dumpsite ONLY at Black Rock Campground on the edge of the park. This is the only campground has any facilities and cell coverage and it is barely inside the park . There is limited water ranger station as you enter and none inside the park so it is best to come prepared. The cell coverage disappears shortly after you enter the park and go up in elevation.
I have never experienced such silence as I have in this area. When the wind is not blowing the silence is so dense and complete that it seems to have matter.
Jumbo Rock Campground is set among large rock formations and has many scenic sites. We were able to walk directly out of our campsite and explore in several directions so most of our explorations were directly from our campsite or from a trail leading to Skull Rock from our campground. . The GPS on our phones were helpful to find our way back easily to our camper since we were not on trails.
