Tucked away in the rolling hills of southeastern Arizona is a hidden treasure.Patagonia Lake State Park was established in 1975 as a state park and is an ideal place to find whitetail deer roaming the hills and great blue herons walking the shoreline. The park offers a campground, beach, picnic area with ramadas, tables and grills, a creek trail, boat ramps, and a marina. The nearby Lakeside Market offers boat rentals and supplies. The campground overlooks the lake where anglers catch crappie, bass, bluegill, catfish, and trout. The park is popular for water skiing, fishing, camping, picnicking, and hiking. And the tracks of the New Mexico/Arizona railroad lie beneath the lake and remnants of the old historic line may be found at the Nature Conservancy in Patagonia. Hikers can stroll along the creek trail and see birds such as the canyon towhee, Inca dove, vermilion flycatcher, black vulture, and several species of hummingbirds.
