The Loop - Tucson and Pima County

The Loop - Tucson, Arizona


The Rillito River bike path also known as “The Loop” is a great ride along the river beds of Tucson. The Loop is considered to be one of the best rides in Tucson, Arizona, connecting the Rillito, Santa Cruz, Pantano River Parks with the Julian Wash and Harrison Road Greenways.

The Loop is a favorite route for locals as a great way to get across and around and through Tucson without having to deal with traffic and lights. Many people believe that it's the safest way to travel across town by bike. For the most part, both sides of the river have a bike path, so you can choose either side of the river to ride on, and mix it up.


This loop is a system of paved, shared-use paths and short segments of buffered bike lanes.

The grade will gradually increase for a period and then starts to drop into a mellow descent and levels out for the rest of the ride.


The loop can be accessed from various places, and you can jump in and out of the loop at various points.

More details

The Loop extends through unincorporated Pima County, Marana, Oro Valley, Tucson, and South Tucson. The connections are the result of Pima County's cooperative partnerships with these jurisdictions.
