About South Mountain Park/Preserve
At more than 16,000 acres, South Mountain Park/Preserve is one of the largest municipally operated parks in the country, according to the Trust for Public Land. It boasts 51 miles of primary trails for horseback riding, hiking and mountain biking for all ability levels. From the park's main entrance, you can drive up the Summit Road 5.5 miles to Dobbins Lookout and spectacular valleywide views or you can continue to the Gila Lookout for a view of the Gila River Valley. This scenic road is shared by bikers and hikers and there are many steep sections and blind curves, so maximum speed is 25 mph and 15 mph on curves.
To learn more about South Mountain Park/Preserve view an Emmy Award winning video or listen to a podcast with Phoenix parks rangers.
Mount Suppoa (not accessible to the public) reaches 2,690 feet. Dobbins Lookout, at 2,330 feet, is the highest point in the park accessible by trail or public roadway.
It is important to remember that the Phoenix mountain preserves are open, undeveloped desert areas. Please use care when heading out as hikers can encounter rocky terrain, rattlesnakes and other potential hazards native to the Sonoran Desert. If you encounter a rattlesnake, allow it space and time to escape. South Mountain Park/Preserve actually consists of three mountain ranges, the Ma Ha Tauk, Gila and Guadalupe. They stretch diagonally from northeast to southwest. Diagonal mountain ranges that protrude from desert floors, like those of South Mountain, are typical features of the Sonoran Desert. Various minerals were mined in the park in the early 1900s before its designation as a park.

*** Hiking during hot-weather months. Please use extra caution if you’re planning on using trails during hot weather months, try to wait for shade when hiking as full sun temperatures can be more than 20 degrees higher than the official shade temperature. So hike in early morning or near dusk when there’s more shade and less intense heat. Remember, even if you are hydrated you can still suffer from heat-related illness on the hottest days. During excessive heat warnings, consider whether it's safe to hike at all. Follow our full safety guidelines for staying safe on the trail.
