How Did the Tom’s Thumb Hiking Trail Get Its Name?
Tom’s Thumb, as you can guess, looks like a thumb! However, this famous landmark was named after a local rock climber from the Arizona Mountaineering Club named Tom Kreuser.

What Should I Expect on Tom’s Thumb Hiking Trail?
Tom’s Thumb begins as a relatively flat walk through the desert but quickly begins to gain elevation after the first few minutes.
For the first mile, you’ll be hiking along a wide dirt path that allows hikers to simultaneously trek up and down the mountain. This part of the trail is the most challenging since you’ll be scaling the mountain, but the path is well-maintained, so you’ll be walking on gravel and won’t be required to step over any giant boulders.
Once you’ve finished the first mile, the trail will begin to level out, and you’ll start your hike into the mountain range. You’ll trek through tons of large boulders, dip into washes, and climb small hills. It’s tucked away inside the McDowell Mountains, so it’s a unique part of the hike with exciting features.
It gets a little rockier when you get to the trail’s end. Once you climb through the rocky portions of the trail, you’ll see Tom’s Thumb! There are plenty of boulders where you can rest, spot the parking lot you just climbed from, and admire your progress.
When you’re ready, you can head back down the way you came—just watch your step on the steep downhill portion during the last mile.
