Patagonia Lake offers a 265-acre paddling destination in southern Arizona's Sky Island country at 5,400 feet elevation. The lake features two distinct sections: the east end is a no-wake zone ideal for paddling, while the west end allows motorized traffic. A marina serves as the primary launch point, where paddlers pass under a wooden rainbow bridge before accessing the main body of water.

Though relatively small - paddlers are never more than 300 meters from shore - the lake's numerous small canyons create an engaging 5-mile circumnavigation route. Red rock formations and desert vegetation line the shores, while the surrounding hills provide a scenic backdrop.

The lake is renowned for bird watching opportunities, with frequent sightings of great blue herons, kingfishers, vermilion flycatchers, and various hummingbird species. Wildlife viewing includes opportunities to spot peccaries (wild pigs) foraging along the shoreline. Early mornings provide optimal conditions for both wildlife viewing and calmer waters.

Facilities include a marina offering kayak and canoe rentals, boat ramps, and a campground with electric hookups and shower facilities. The nearby Lakeside Market provides supplies. Day use fees apply, and the park gates operate from 4 AM to 10 PM.

Notable regulations include the prohibition of personal watercraft (jet-skis), waterbikes, above-water exhaust boats, and V-8 jet boats. Water skiing is allowed on weekdays year-round but restricted on weekends and holidays from May through September due to congestion.

The lake was created in 1968 by damming Sonoita Creek, with remnants of the historic New Mexico/Arizona railroad lying beneath its waters. The area became a state park in 1975 and continues to serve as an important recreational resource in southern Arizona.
