A day use fee of $5 per vehicle (2019) is charged for hiking, parking alongside the road or using the picnic areas, but there is no fee for brief stops at roadside overlooks, visiting Summerhaven or parking at the Ski Center, nor for any visitor on foot/bicycle/horseback. Coronado National Forest campgrounds charge $10 per night.
The Scenic Drive
The Catalina Highway (also known as the General Hitchcock Highway, after Postmaster General Frank Harris Hitchcock who organized its construction) starts towards the east side of Tucson and crosses the suburbs for several miles to the edge of the hills, where the surroundings change quite abruptly to dense forests of saguaro, palo verde bushes and other cacti.
The road begins to climb, winding around several small ravines then runs alongside steep-sided Molino Canyon, containing a seasonal stream (Agua Caliente Wash) that forms waterfalls and cascades in spring. The cacti fade away above 4,000 feet to be replaced by open, grassy hillsides as the highway crosses the flat land of Molino Basin, location of the first of five campsites close to the road. Next is another climb, of 1,000 feet, over rocky slopes bearing yucca and occasional small bushes, into the upper end of Bear Canyon and through patches of pine/oak woodland, site of a second campground and a picnic area. From here the road switchbacks southwest, ascending high above the canyon to a grand overlook at Windy Point (6,600 feet), next to some unusual eroded rock pinnacles, from where a vast area of land to the west is in view. Turning sharply back northeast, the land is bush-covered for a while, part of the chaparral zone, but round a corner becomes quite densely-wooded with ponderosa & Arizona pine trees, and groves of aspen, and remains so for the final 15 miles to the summit, though still with frequent sweeping views both east and west.
The road passes a cluster of houses at Willow Canyon and several more campgrounds before reaching a left turn that leads to the village of Summerhaven, in a sheltered, wooded ravine - the far upper end of Sabino Canyon. The village has hundreds of homes, some only occupied for a few weeks each year, several shops, a post office, restaurant, cafe and various lodges. Near Summerhaven a dirt track forks off, descending the northern slopes and meeting a paved highway again at Oracle; this is the only other road to the mountain, though is suitable for 4WD vehicles only. The main road ends just 1.5 miles further at a parking area next to the ski center, though a narrower road continues to the actual summit, on which are built various non-public buildings including an observatory. An alternative way to reach the top is to walk half a mile up the main ski run, a steep but enjoyable climb of 650 feet through the forest. The summit, like some of the lower hillsides, bears many trees burnt in a big wildfire of June 2003, and so presents a rather barren appearance, with the blackened tree stumps mingling with assorted radio masts and satellite towers. Over 10,000 trees are to be planted along the highway to partly replace those consumed.
In good winters when the mountain approaches its average snowfall of 200 inches, Mount Lemmon Ski Valley is open from mid December to early April, offering 2 double chairlifts and 20 ski runs, with a longest vertical drop of 900 feet. Instruction and equipment rental are provided, and overnight accommodation is available in nearby Summerhaven. But in recent years the snow has arrived late and lasted just a few weeks so the ski season has been much shorter.
