“A stiff climb on desert singletrack leads to fantastic views of Toms Thumb and the surrounding area”
— Hunter R
There is absolutely no water at the trailhead, so you'll need to bring it with you. I recommend 2 liters at the very least for this ride, if not 3, due to the stiff grades and punishing, shadeless environment along the route.
Jump on Tom's Thumb for a trail experience that will test your climbing mettle.
From the trailhead parking area, the Tom's Thumb trail starts just on the other side of the shade facility, complete with restroom and kiosks detailing the local flora, fauna, and geology.
After getting geared up and checking your tubeless sealant (there's plenty of thorns if you deviate from the trail here), head up the trail as it meanders along a wide path through vibrant cholla, saguaro, and flowering ocotillo.
