Sweetwater is a beautiful and easy trail to start riding in Tucson. There aren’t too many rocks, drops, sand traps, or climbs to challenge beginner riders. Plus, you’re riding through mature saguaros, which is what you’ve traveled (or moved) to Tucson for.
New riders will want to start on Saguaro Vista Trail (1.1 miles) and take it to Black Rock Loop (1.6 miles). If you’re still feeling good, tack on Sun Loop Circle (.5 miles) (note: it customary, and kind, to ride these loops clockwise). New riders can lather-rinse-repeat these sections until they feel the burn.
When you’re ready to level up, take the steady climb up the Lost Arrow Trail (.6 miles). Then take the Homestead Trail (.9 miles) into the southern part of the park and return via Red Tail Ridge (1.2 miles) – Oxbow (.4 miles) – Wildflower Ridge (.4 mile). This route is intermediate, but not sustained, so you can hike a bike over the obstacles. The other side loops and spurs here are fun to explore too, but be careful of the top of The Spine, because it’s a fast and sustained rocky downhill. Be sure to load the Sonoran Desert Mountain Bike map onto your phone before leaving to keep from getting lost.
