You’ve seen the iconic saguaro cacti, the endless desert sky, and the rattling heat of southern Arizona. But there’s a road near Tucson that flips the script on everything you thought you knew about Arizona.
The Catalina Highway is one of those drives that feels like a secret. In just 28 miles, it takes you from the desert floor to the alpine forests of Mount Lemmon.
The heat of Tucson’s sun gives way to the chill of high mountain air. The desert transforms into a forest. Saguaro cacti turn into towering pines. And the best part? This entire shift happens as you climb.
It’s a road that shows you Arizona like few others can. The Catalina Highway is a snapshot of the state’s drastic changes in elevation and scenery.
From 3,000 feet in Tucson, you’ll ascend to 9,200 feet at the top of Mount Lemmon, passing grasslands, rocky canyons, waterfalls, and eventually snow-capped peaks.
Our Road Trip Starts With Desert
When you begin your trip in Tucson, you’re at the base of the Santa Catalina Mountains, surrounded by saguaros and dry desert.
The temperature here can easily reach 100°F in the summer, and the landscape feels vast and endless. You’ll find yourself driving through dusty roads with wide-open spaces and dramatic desert scenery.
The climb begins at 3,000 feet, but as you ascend, the temperature drops. By the time you pass 6,000 feet, you’ll start seeing grassy meadows, rocky outcrops, and groves of oak and juniper trees.
The air feels cooler, and you begin to see what makes this road so special. This is more than just a drive. It’s a chance to see multiple ecosystems in one trip.
The Best Stops Along the Way
Babad Do’ag Overlook
At 3,600 feet, this overlook is one of the best spots to start your climb. Babad Do’ag means “frog mountain” in the Tohono O’odham language, named for the shape of the mountains that rise above.
From here, you get panoramic views of Tucson and the Rincon Mountains. You can hike nearby trails or just take in the scenery from the pullout.
Molino Canyon Vista
By 4,500 feet, the landscape has changed again. Molino Canyon is where desert meets grassland.
Here, you’ll find a creek that runs with snowmelt, and during monsoon season, waterfalls emerge. If you’re lucky, you might spot wildlife like javelina or mule deer, especially in the early morning or late evening.
Thimble Peak Vista
At 5,000 feet, you’ve reached a high point with amazing views of canyons, rock formations, and the distant peaks. Thimble Peak, a pointed rock formation, dominates the vista.
This stop is great for birdwatching or just taking in the fresh mountain air. The smell here changes depending on the season, from wildflowers in spring to the fresh scent of pines.
Seven Cataracts Vista
If you visit after a rainstorm or in spring when the snow melts, you’ll be treated to the Seven Cataracts waterfalls.
This stop is well worth the detour, offering breathtaking views of cascading waterfalls as they flow down the canyon. It’s quieter here, making it an ideal spot for stargazing, too.
Windy Point Vista
At 7,000 feet, Windy Point gives you one of the best views on the Catalina Highway. You can look out over Tucson, the surrounding desert, and the other mountain ranges.
It’s a great place for a sunset, but the view at night is just as impressive when the lights of the city twinkle below.
Summerhaven and the Top of the Mountain
By the time you get to Summerhaven, you’ve reached the top of the mountain. The village, at 8,000 feet, is a retreat from the summer heat in Tucson. In winter, it’s a snowy wonderland, and in summer, it’s cooler by at least 30°F.
Summerhaven is home to small shops, restaurants, and rental cabins. You can grab a cookie at the Cookie Cabin or check out local goods at the general store.
If you’re looking for a quiet spot to enjoy the mountain, head to Marshall Gulch, a picnic area with hiking trails through pine trees and ferns.
The Legacy of the Catalina Highway
Catalina Highway isn’t just a scenic drive. It’s a road built on layers of history. The highway was constructed in the 1930s to make access to Mount Lemmon easier. Before that, travelers had to take the narrow, rocky Oracle Control Road.
But the story of the highway’s creation isn’t all smooth. Prison labor was used to build the road, which adds a darker chapter to its history. During World War II, the same site was used as an internment center for conscientious objectors and Japanese Americans.
When the road was finished in 1950, it opened up access to Mount Lemmon and Summerhaven, making it possible for people to escape Tucson’s scorching summer heat. The highway transformed Tucson’s relationship with the mountain, making it an easier retreat.
So, when you’re driving up Catalina Highway, remember that it’s more than just a way to reach the top. It’s a route that’s tangled with Tucson’s past.
Check the Weather Before You Go
Even though Catalina Highway is mostly paved and easy to navigate, it’s important to check the weather before heading out.
In the winter months, snow and ice can make the road tricky to drive, especially at the higher elevations. Monsoon rains during the summer can also cause flooding on parts of the highway. Be sure to check road conditions ahead of time.
The Pima County Sheriff’s Department will close access to the road when conditions are too dangerous, so it’s a good idea to stay updated on any closures.
You don’t need a high-clearance vehicle to drive Catalina Highway, but it’s a narrow, winding road in spots. Take it slow and drive with caution. Always be prepared for sudden weather changes, as the conditions can shift quickly in the mountains.
