We spent four days exploring Joshua Tree National Park. We mostly drove around (it’s a BIG park) but we also did some hiking and backpacking. It was Spring, and there were many wildflowers, although we arrived just as a heat wave struck. We had a fun time and would gladly return (with cooler weather).
