Split in half by the bustling metropolitan city of Tucson, Arizona, Saguaro National Park (pronounced sa-WAH-ro) gets its name from the characteristic cacti that grow within its borders. The largest type of cactus in the nation, can live up to 200 years, even in the sweltering Sonoran Desert. The park features two districts: Rincon Mountain District (RMD) in the east and Tucson Mountain District (TMD) in the west. Saguaro outcroppings are most common in TMD, while RMD's Sky Islands (isolated mountain ranges) are home to cougars, bears, and coatis. While Saguaro National Park doesn't offer RV camping, you can still hike to the park's six walk-up backcountry campgrounds in hopes of spotting a bobcat, groups of javelinas, mule deer, and coyotes. Harvest Hosts has plenty of locations within an hour of the entrances where you can park your RV overnight at a working farm, brewery, or distillery.
Harvest Hosts is a membership program for RV camping: unlock unlimited overnight stays at thousands of locations.
Learn MoreThe Arizona sun scorches all beneath it between 10 a.m. and 4 p.m. on hot summer days, when the mercury rises well over 100 degrees Fahrenheit. Starting in the middle of July through the end of September, the summer monsoon precipitation often brings some relief, which many mating animals take advantage of. The park's busiest months fall between November and March, though the saguaros typically bloom from late May through July. Earlier or later in the day and during late spring and winter are often the best times to go. Temperatures typically don't drop below 50 to 60 degrees Fahrenheit during the winter months, although it still snows.
Phoenix is just north and west of Saguaro National Park, about an hour's drive up Interstate 10. Tucson's northeast is bordered by the Santa Catalina Mountains, including Mount Lemmon. If you're winter RVing in southern Arizona, stop in at the Pima Air & Space Museum any day of the week to see amazing feats of aviation. Also in Tucson, the Reid Park Zoo is a great place for sightings of not-so-native animals like lions, flamingos, elephants, and giraffes. Further south lies the Coronado National Forest across Interstate 10, as well as Kartchner Caverns State Park. Saguaro National Park is also only about 60 miles from the U.S.-Mexico border.
Inside the park. There is no RV camping in Saguaro National Park. Vehicles cannot drive up to the campsites, as they're only accessible by hiking in. Choose from Manning Camp, Juniper Basin, Happy Valley Saddle, Spud Rock Spring, Grass Shack, and Douglas Spring Campgrounds. Of the half dozen of them, Spud Rock Spring is the most isolated at 7,200 feet in elevation. Miller Creek Trailhead is close to Happy Valley Saddle, but some hikers choose Juniper Basin for the punishing hike up the Tanque Verde Ridge. Manning Camp was previously the former Tucson mayor's summer home.
Tips on reserving a campsite. Backcountry camping isn't available in the Tucson Mountain District of Saguaro National Park. You must make reservations to camp at the walk-up sites in Rincon Mountain District.
Camping outside the park with Harvest Hosts. Since RV camping in Saguaro National Park isn't permitted or supported, RVers stay outside the park, typically within 30 minutes to an hour away in nearby Arizona RV campgrounds for quick access. Since the park stays open year-round, campsite availability and corresponding services vary. Many RVers opt to stay with a nearby Harvest Host, who offers free camping on private property in exchange for patronizing their working farm, brewery, local attraction, or distillery.
