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 campground overlooks a 265-Acre man-made lake where anglers catch crappie, bass, bluegill, and catfish. Trout is stocked every three weeks from October through March. 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 beautiful creek trail and see a variety of birds such as the canyon towhee, Inca dove, vermilion flycatcher, black vulture, and several species of hummingbirds. At two and a half miles long and 250 surface acres, Patagonia Lake State Park is popular for a variety of recreational activities, including water skiing, fishing, camping, picnicking, and hiking.
