The Rillito River Park Trail runs for many miles (about 12 miles) along the Rillito River, from Craycroft Road to under I-10 and linking with the Santa Cruz River Park Trail. This "River" is empty of water for most of the year (so you will see people riding horses in the bottom often. It fills up from Mountain rains only a few times a year.) Most of the trail "above" is paved in asphalt. The trail is open from dawn to dusk.
Cyclists can also use this trail, staying on their side of the trail. Additionally, there is a Children’s Memorial Park at a section of this trail, located between Oracle and La Canada, off North 15th Place.There are restrooms and drinking fountains, as well as exercise stations along the trail (between Oracle Road and La Cañada Drive). You can park near the trail in several places along its route (near Craycroft Road, just west of Swan Road, at Brandi Fenton Park (off Alvernon Way), off Campbell across the street from Trader Joes Grocery, by Children's Memorial Park just south of Edgewater Drive, at the end of River Fringe Drive, at the end of Shannon Road, and off Camino de la Terra just south of River Road.)
