Tucked away in northeast Tucson’s quiet residential area lies a 101-acre desert oasis that feels more like a Los Angeles park than something you’d find in Arizona.
This unique regional park centers around perennial warm springs that have sustained human and animal life for over 5,500 years, creating a lush island of towering palm trees and wildlife-rich ponds in the heart of the Sonoran Desert.
Natural Wonder
Historic Warm Springs: The literal translation “hot water” (agua caliente) describes springs that once flowed at 500 gallons per minute.
While recent drought and development have reduced flow to barely a seep, the geological mystery continues as underground heat sources hundreds of feet below still warm the water.
Three Pristine Ponds: Crystal-clear ponds fed by spring water (now supplemented by wells) create perfect wildlife habitats. The warm water temperatures support an exceptionally rich ecosystem rarely found in desert environments.
