Roadrunners, Gila Monsters, and Owls in Saguaro National Park
Saguaro National Park surrounds Tucson in two very different districts. To the west, the Tucson Mountain District protects rugged volcanic hillsides packed with towering saguaros. East of the city, the Rincon Mountain District stretches from the Sonoran Desert into higher elevations where oak woodland and pine forest eventually replace cactus.
We visited both sides of the park in August, when daytime temperatures easily climbed into the triple digits. The heat kept most of our hikes short, but the summer monsoon had transformed the desert. Recent rain left the landscape greener than we expected and brought out wildlife that made every outing worthwhile.
Saguaro West
Our first stop was the Valley View Overlook Trail, where saguaros covered the hillsides in every direction.
An American Kestrel perched on top of one towering cactus while Gila Woodpeckers, Gilded Flickers, and Cactus Wrens called from all around us. Even during the hottest part of the day, the desert never felt completely quiet.
We didn't venture far before the heat convinced us to turn around, but the wildlife continued to surprise us. Several Mule Deer wandered through the saguaros, and just before reaching the parking area, a Greater Roadrunner stepped into view and paused long enough for us to enjoy an unusually good look. Later that day another Roadrunner lived up to its reputation by sprinting alongside the road before disappearing into the desert.
The visitor center became a welcome place to cool off with air conditioning and cold water. A Curve-billed Thrash perched high on a kiosk and watched its fledgling look for bugs! Outside, as should be expected on a super hot day, Zebra-tailed Lizards darted across the pavement, raising their banded tails high enough to flash their bold black-and-white pattern.
Saguaro East
We found ourselves returning to the Rincon Mountain District several times during the trip. Driving the Cactus Forest Loop slowly gave us the chance to watch washes, road edges, and open desert for wildlife, while shorter walks on trails like Loma Verde let us experience the landscape on foot before the heat became overwhelming.
Our most unforgettable encounter came right next to the trail when we had decided it was too hot to be outside and it was time to go back to our Airbnb. Poof, we stopped looking and the most wild creature ran right next to the trail!
A Gila Monster emerged from the vegetation and slowly worked its way through the desert. Its heavy body, beaded black-and-orange skin, and deliberate movements gave it an almost prehistoric appearance.
Because Gila Monsters are just not frequently seen, seeing one in the wild is a privilege. We watched quietly from a respectful distance until it disappeared back into the surrounding brush.
After Sunset
Common Poorwills called across the cooling desert while toad appeared on the warm pavement after monsoon rains. We drove slowly, stopping several times to let the toads hop across the road. They were hopping out one after the other! We saw Red-spotted Toads and Sonoran Desert Toads!
But my favorite moment… A young Great Horned Owl stood on top of a large boulder, calling repeatedly as it waited for an adult to return. It shuffled awkwardly across the rock, looking like a recently fledged kid still trying to figure things out. When the adult finally appeared nearby, the young owl had the most outrageous vocalizations making sure it was noticed! I didn’t get great photos with the darkness, but enough to help me remember this funny scene for a long time!
Visiting Saguaro National Park in August meant accepting shorter hikes and planning around the heat, but the monsoon season gave us a side of the Sonoran Desert we hadn't expected. Between the Roadrunners weaving through the saguaros, the unforgettable Gila Monster, and a young owl calling into the evening, the park felt wonderfully alive despite the summer temperatures.
