NEW! I Hike For Health Challenge:

Come hike the Green Desert and earn a reward for being active in Organ Pipe Cactus.

There are miles and miles of trails laced around Organ Pipe Cactus National Monument. Some are easy, others are strenuous, most of them fall somewhere in between. Some of the best hiking is off the beaten trails and out in the canyons with a map and compass to guide you. Always carry water and snacks, and avoid hiking during the hottest parts of the day. More detailed trail information is available in the park newspaper and in person at the Kris Eggle Visitor Center.

Backcountry Camping

Backcountry camping is available in designated areas. Check with the Kris Eggle Visitor Center for more information.
