This is the shortest/steepest way to ascend/descend the McDowell mountain ridge. If you choose to climb this, you're looking at 1 to 1.5 miles of hike-a-bike, depending on your tolerance for mounting up for short distance efforts. The trail is more appropriate as a descent, though it is by no means easy. What makes it tough are the too-tight switchbacks and the kitty litter trail surface. Rocks are not much of an issue. The trail is heavily hiked, especially on weekends, and the trail is not generally wide enough for comfortable passage.

Access Info

Tom's Thumb trailhead--this leads to the climb. To access the descent (w/o the climb), climb the Tom's Thumb trail on the W side of the ridge, most likely from the Gateway trailhead.

       So I read the TrailForks description of this trail, and we decided to ride it any way. OK - best description I can relay is HUMBLING. Yes the trail was packed with hikers, but that did not affect me at all - only challenges I had were physics and gravity. Make no mistake - THIS IS ABOUT AS STRAIGHT UP AS YOU CAN GET WITHOUT AN ELEVATOR!. Steep - YES groomed trail YES (dusty with kitty litter type crushed granite all over narrow - YES; hikers - YES (Lots of them - EVERYONE ONE OF THEM WAS SUPER COOL AND SUPPORTIVE!!); other MTB'ers - JUST ONE NUT (going up for his 3rd time that day!). To say we did it, worth it I guess, no plans to ever do again and knowing then what I know now, I probably would not have gone up..... +probably ;-D

       Hey, I resemble that remark! I just checked my log on Strava, and I rode up (and down) the Thumb three times on 4/22/17.
