Mount Lemmon

The Catalina Highway is the heart of a Mount Lemmon trip. It begins in the low desert on the northeast edge of Tucson among giant saguaros and continues up through rocky slopes studded with strange hoodoos and balanced boulders, past overlooks that gaze back over the city and the desert basin. As it climbs, the plants change: cactus gives way to scrub, then to oak and juniper, then to tall pines, and finally to fir and aspen near the summit.

Ecologists like to say that driving up Mount Lemmon is like driving from the deserts of Mexico to the forests of Canada, passing through several distinct life zones in the space of a few dozen miles. Each turnout offers a new view and a slightly cooler, greener world, making the highway itself the main attraction, a road that packs a continent of scenery into a single afternoon.

The Santa Catalinas are one of the great sky islands of southern Arizona, ranges that stand tall enough to gather the moisture and cool the air needed for high-country forests, cut off from other mountains by seas of desert. Because they are isolated, these ranges shelter unusual mixes of plants and animals, some stranded here since cooler, wetter ages long past.

On the upper slopes of Mount Lemmon grow ponderosa pine, Douglas fir, and quaking aspen, home to black bears, mule deer, wild turkeys, and mountain birds rarely seen in the desert below. The isolation makes each sky island a natural refuge and a place of scientific interest, a green island floating high above the tan sea of the Sonoran Desert.

Near the top of the mountain sits Summerhaven, a small forest village of cabins, a general store, and a few eateries, a cool retreat where Tucsonans have long escaped the summer heat. It is a modest place with a resilient spirit, having weathered a major wildfire years ago and grown back, and it makes a pleasant stop for a meal or a slice of pie before heading higher.

Above the village, near the summit, is one of the southernmost ski areas in the country, where in a good winter the mountain gathers enough snow for a small run, an unlikely sight above a desert city. Whether covered in snow or shaded by summer pines, the top of Mount Lemmon feels a world away from the desert below, cool and quiet under a high sky.

Summer is when Mount Lemmon shines brightest in local hearts. As Tucson bakes, the mountaintop can be many degrees cooler, and city dwellers pour up the highway to picnic, hike, and breathe mountain air. Afternoon storms can build over the high country in the monsoon season, so an early start is wise.

Fall brings golden aspens near the summit and crisp, clear days ideal for the drive and the trails. Winter can dust or blanket the top with snow, opening the little ski area and turning the summit into a novelty for desert dwellers, though the upper road may ice up. Spring is mild and green, a fine time for hiking as wildflowers appear, making the mountain rewarding in every season for anyone seeking a break from the desert below.

Mount Lemmon is the highest peak in the Santa Catalina Mountains near Tucson, Arizona, rising to around nine thousand feet and offering a remarkable escape from the desert heat below. A scenic drive climbs from saguaro-studded desert through several life zones to cool pine forests at the top, a change likened to driving from Mexico to Canada in an hour. With hiking, camping, rock climbing, the small village of Summerhaven, and even a ski area in winter, Mount Lemmon is a beloved year-round mountain playground for the Tucson region.

You can drive the stunning Catalina Highway with its many scenic overlooks, hike trails through forest and past rock formations, enjoy cooler temperatures in summer, visit the mountain village of Summerhaven for a bite or a treat, go rock climbing at popular crags, camp among the pines, and in winter, ski or play in the snow at the small ski area. Fall color and spring wildflowers add seasonal beauty. The dramatic change from desert to alpine scenery makes the drive and its activities especially rewarding.

The Catalina Highway up Mount Lemmon is famous for climbing through a stunning succession of ecological zones, starting amid Sonoran Desert saguaros and cacti and ascending through grassland, oak, and finally cool pine and fir forest near the summit, so the scenery and even the temperature transform dramatically over the drive. Numerous pullouts offer sweeping views and striking rock formations along the way. This rapid journey from desert to mountain forest, all in one road, makes the drive one of the most scenic and memorable in southern Arizona.

Mount Lemmon is a year-round destination with something in each season: summer offers a cool escape from Tucson's heat, making it especially popular then, fall brings color, winter can bring snow and skiing at the small resort, and spring offers wildflowers. Because temperatures at the top can be dramatically cooler than in the desert below, bring layers whenever you go. Checking road and weather conditions is wise in winter, when snow and ice can affect the drive. Any season rewards a visit.

Mount Lemmon rises above Tucson, near Sabino Canyon in the Santa Catalina foothills, Saguaro National Park's eastern district, and the attractions of the city, with the Arizona-Sonora Desert Museum and Saguaro West on the far side of town. That makes the cool heights of Mount Lemmon an easy and refreshing contrast to combine with Sabino Canyon, the saguaro forests, and the many other natural and cultural attractions of the Tucson area on a visit to southern Arizona.
