Hiking Arizona: Tom’s Thumb-Scottsdale McDowell Sonoran Preserve


Scottsdale McDowell Sonoran Preserve is one of my favorite places to hike for a lot of reasons; trails that vary from easy to extremely difficult, most of the views are nothing short of breathtakingly amazing, and the opportunity to see desert wildlife, plants, wildflowers (when they are in bloom) and cactus are endless. The Sunrise, Lost Dog, and Gateway Trailheads are an easy 10-20 minute drive from my home in Fountain Hills, so I tend to stick to them. I have my favorite “go to” hikes at each of these trailheads.

Last Monday I was feeling the stress from an upcoming buyer closing that was scheduled for Wednesday. The loan docs weren’t out of underwriting approval or at title yet. Rather than sit around freaking out or calling and texting the lender every 5 minutes, I decided to venture out to someplace I hadn’t been in a while, the Tom’s Thumb Trail. There are several different hiking options here. The Tom’s Thumb Trail is a 5 mile out, 5 mile back, extremely difficult, 10 mile round trip hike. I have not hiked it in its entirety yet. I have hiked out to the Thumb, over to the Lookout and back to the trailhead, a 5.9 mile round trip hike, and from the Tom’s Thumb Trailhead to the Gateway Trailhead, a 7.5 mile one way hike in the past. Since the drive there takes about 45 minutes and I was somewhat pressed for time, I planned to hike from the Trailhead to the Thumb and back. A fairly short, but challenging hike that I could complete in 2 hours.

The trail starts of easy. Some cactus were in bloom for me to enjoy as I started out.

.4 mile from the trailhead there is a turn off for the Feldspar Trail. Keep straight. The trail continues to get steeper and there are several switchbacks to climb. The next sign you will see says 1.1 miles to the Thumb (actually, it is another .3 miles in addition to that, but who’s counting?). You are about .9 miles into the hike at this point. Continue hiking up another .7 miles or so and you will reach the turn off for the East End Trail. Be sure to take in all of the unusual rock formations along the way.

Continue on from there another .3 miles. At this point you will come to a sign directing you turn to go .3 miles up to the Thumb.  Continue on for .3 miles and you have arrived!

I have been told that if you continue hiking to the left, or West of the Thumb and follow the trail almost until the mountain begins to drop, you will find Ogre’s den, a cave formed by fallen boulders. Inside the cave there artifacts and a hiker’s sign-in log book. I left that exploration for another trip.

Path leading to Ogre’s Den is between these rocks
