Most people think of Mount Lemmon as a day trip from Tucson — drive up, get cool, drive back. That's selling it short. Mount Lemmon is a full camping destination, and if you find the right dispersed site up here, it's one of the most rewarding camps in southern Arizona.

The Santa Catalina Mountains form one of the largest sky islands of southern Arizona — hills that rise far above the Sonoran Desert plains and harbor climate zones typical of lands much further north. From ancient paleo-Indians 4,000 years ago to the complex Hohokam culture a thousand years ago, the Spaniards of the 1542 Coronado Expedition, and the Apaches and 19th century pioneers of Arizona's Territorial Period, Mount Lemmon and the Catalina Mountains have been sought out by people seeking woodland resources and a respite from the scorching desert floor. That same impulse drives the tens of thousands of Tucsonans who head up here every summer.

The Catalina Highway — Sky Island Scenic Byway

The Catalina Highway — officially the General Hitchcock Highway — is a 27-mile scenic route that ascends from the desert floor in Tucson to near the summit of Mount Lemmon, gaining over 6,000 feet in elevation and showcasing a variety of climates ranging from lowland desert to alpine forests. The drive simulates the experience of driving from Mexico to Canada — pullouts along the way offer exhibits and panoramic views of Tucson and the surrounding mountains. Allow at least one hour of drive time plus stops. The road is winding with blind turns — drive with care and watch for wildlife and cyclists.

The road can close for snow or fire danger — call the road hotline at (520) 351-3351 for current conditions before making the drive.

Dispersed Camping — FR 34 (Mount Bigelow) & FR 3 (Incinerator Ridge)

The two best dispersed camping roads on Mount Lemmon are where we camped — E Mount Bigelow Road (FR 34) at milepost 21 and Incinerator Ridge (FR 3) at milepost 19. Both are free, no reservations, no facilities, and closed December 15 through March 30. Dirt road access — a standard truck or SUV handles these roads fine in dry conditions.

FR 34 takes you up toward Mount Bigelow in mixed conifer at around 8,000 feet. FR 3 / Incinerator Ridge sits just below that elevation with forested sites and a more open ridge feel. Both roads offer the kind of quiet, away-from-the-highway camping that the developed sites on the main road simply can't provide. Come up on a weekday if you can — weekends bring significant traffic to the main highway.

Two other dispersed areas worth knowing: Bear Wallow at milepost 23 and Radio Ridge above Ski Valley — both free, same December 15–March 30 closure dates. N. Oracle Control Road dispersed area is accessible from the junction at milepost 24.5.

Summerhaven

Near the summit is the village of Summerhaven with sit-down restaurants and local food trucks — a genuine mountain village less than an hour from downtown Tucson. It's a welcome stop after a morning of hiking or before heading back down. The Palisades Visitor Center nearby has a bookstore, hosts, and exhibits worth a stop.

Mount Lemmon Ski Valley

Near the summit is a ski center — the southernmost skiing area in the USA, since temperatures on the mountain are up to 30°F cooler than in Tucson. In winter and spring, the ski area draws crowds. In summer the chairlift sometimes operates for sightseeing. Worth knowing about even if skiing isn't your thing — the summit views are exceptional.
