Tucson is known as one of the most bicycle friendly cities in the U.S., according to NPS. Riders go to the park in the winter because of the nicer weather. You’ll see native plants and animals while surrounded by the spectacular scenery of the Sonoran Desert. The 3 miles of doube-track in the park are attached to the 800+ mile Arizona Trail from Utah to Mexico. Bicycle Adventures has a 6-day Cactus Classic Bike Tour during which you spend a day in Arizona’s Saguaro National Park, where the cacti soar nearly 50 feet in height. Tucson Rentals offer a variety of trips as well.
