A brilliant blue blip dolloped into the mountains, 2.5-mile-long Patagonia Lake was formed by the damming of Sonoita Creek. About 7 miles southwest of Patagonia, the lake is open year-round. At 3750ft above sea level, buffeted by lake and mountain breezes, the air is cool – making this a perfect spot for camping, picnicking, walking, bird-watching, fishing, boating and swimming. The park's campground makes a fine base for exploring the region. The visitor center is also open 7am to 10pm on Fridays from April through October.
Trout, bass, catfish and other species can be caught in the lake, and boats can be hired from the nearby Lakeside Market.
