Joshua Tree · With kids
WITH KIDS
A park of climbable boulders and quarter-mile trails, best treated as an autumn-to-spring destination.
Hidden Valley Nature Trail
A one-mile loop into a rock-walled bowl, with sanctioned scrambling on every side and interpretive signs. An hour well spent from about age four.
Barker Dam loop
About 1.3 miles, flat, past a cattle rancher's dam and a panel of petroglyphs. Water appears after rain and bighorn sheep occasionally come down to it.
Cholla Cactus Garden
A quarter-mile boardwalk through a dense stand of teddybear cholla, glowing at low sun. Keep children on the planks — the segments detach into skin at a brush.
Junior Ranger and stargazing
Booklets from the Oasis or Joshua Tree visitor centres, and a small volunteer observatory near the north entrance that runs public star parties on clear nights.
Heat, water and cold nights
From June to September the park runs 100–110°F and is genuinely dangerous. Visit October to April, carry a gallon per person, and pack layers for the nights.
