“An easy dirt road through Joshua Tree National Park with the chance to get personal with some Joshua Trees.”
— Lost Justpastnowhere
The dirt roads in the Queen Valley area offer a better way to experience the park than through the window of a car, provided of course that it isn't too hot and you've brought plenty of water.
There seem to be more Joshua trees at the western portion of this trail. You'll also have good views of the faraway Transverse Ranges mountains towards the west guarding the outskirts of Los Angeles.
