Joshua Tree in July: what the park service says

July at Joshua Tree means planning around heat. The park suggests hiking before 9 a.m. or after 5 p.m., sticking to short walks such as Barker Dam, Hidden Valley or the Cholla Cactus Garden, and skipping trails longer than two miles, like Ryan Mountain or Lost Palms Oasis. There is no cell service, so tell someone your plans, and do not bring a pet in summer.
