To access this ride, head to the parking area and trailhead at 104th Street/Bell Road. This lollipop-shaped route provides plenty of exercise on the way out, and a lot of fast, fun descending on the way back.

Need to Know

Riding in the desert often takes more energy than visitors realize. Be sure to bring plenty of water and sunscreen, and you might want to avoid this one in the summer heat.


This is one of several great loops in the McDowell Sonoran Preserve, especially for riders looking to get out for a longer ride on tougher terrain.

The approach on Tom's Thumb Trail is pretty much uphill all the time with a few spots that drop into washes. The trail conditions slowly change from loose shale and baby heads to hardpack desert soil. You'll continue around the backside of the loop on the Feldspar Trail, and then take a right onto the Marcus Landslide Trail. This route eventually leaves you at the Boulder Trail, which you continue on before reaching the Coachwhip Trail.

At the first major saddle near the junction for East End Trail, the trail becomes littered with loose, eroding granite (think kitty litter). Windgate Pass Trail is aptly named, as the saddle provides a great spot to take a break and dry off! Once past this point, you'll be able to enjoy a rolling descent all the way back to the parking area where you started your journey.

Mostly clear trails. Tom’s Thumb was a little overgrown in less traveled places. Crowded trails around midday.

Lots of fun sections but Toms thumb should be left to hikers. 19.3mi

Make no mistake this ride has tough sections. Come prepared with lots of water and snacks. Start out as early as possible to avoid hikers and heat. 19mi — 4h 00m

This is probably the toughest trail that I've ridden in the Phoenix metro area. Totally kicked my butt. I'll be for redemption. 11.2mi

Gird your loins, grit your teeth, cuss, swear, sweat... but push on through the tough and largely hike-a-bike uphill portion to Tom's Thumb. The view from up there is fantastic. The decent after TT is great and filled with switchbacks and kitty litter! From there it opens out to the usual smooth kitty litter rolling and mellow madness that are the many McDowell area trails. This leads into another climb with a few small hike-a-bike portions. After that comes the decent down janky sketchy gnarly jagged sharp loose rock with hold on tight for dear life jarring delight.

Not even worth riding in my opinion if you want to actually ride your bike. Decent views, but completely frustrating being around hundreds of hikers (but on a mid-Sunday morning), and hiking up 80% of the trail to the top. Its steep, but the loose rocks are what make it nearly impossible to climb in most parts. Then don't expect to be free of hikers on the descent. I was on trails way off the beaten path and still encountered plenty of hikers. These are hiking trails. It's not worth it for any party involved to ride a bike here in my opinion. Unless you have pro-level technical climbing ability and don't mind stopping for hikers constantly. Mar 6, 2019
