About

Overview

Twin Peaks Campground is located within Organ Pipe Cactus National Monument, in the heart of the Sonoran Desert along the United States border with Mexico. This landscape reveals a thriving community of plants, animals, and human stories that echo throughout this desert preserve, chronicling thousands of years of desert living. A scenic drive, a wilderness hike, or a night of camping will expose you to a flourishing, living desert.

Recreation

Along with photography and birding, hiking is ideal here. There is a 0.9 mile (1.4 km) perimeter trail around Twin Peaks Campground, and the 1.2 mile (2 km) Desert View Trail located near the group camping area. Beyond the campground area, miles of hiking trails lace Organ Pipe Cactus National Monument, some easy, others more strenuous. Some of the best hiking is off the beaten trails 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 person at the Kris Eggle Visitor Center.

Natural Features

Organ Pipe Cactus National Monument exhibits an extraordinary collection of plants and animals of the Sonoran Desert. This is a showcase for creatures who have adapted themselves to the extreme temperatures, intense sunlight, and little rainfall that characterize this Southwest region. Thirty-one species of cacti have mastered the art of living in this place, including the park's namesake and the giant saguaro. Here, the life of the Sonoran Desert is protected and allowed to flourish under nearly ideal wilderness conditions. The monument is an outstanding natural preserve where one of the Earth's major ecosystems survives almost unspoiled.
