Happy Valley Saddle is a three-site, hike-in campground in the Saguaro Wilderness, high in the Rincon Mountains. It serves as a resting point for people climbing Rincon Peak. From Miller Creek, the shortest campground route in the park is about four miles with more than 2,000 feet of climbing. Expect a strenuous backpacking approach, not a roadside night. Both Miller Creek and Turkey Creek trailheads start on Coronado National Forest land; the first 1.5 miles of either approach are outside the park boundary.
