Easy drive and good access to the boundary of the park. Drive only about 15 minutes from downtown to a parking lot with primitive trails. Drive West on Speedway until the road turns into W Gates Pass Rd.
Saguaro National Park East & West
Saguaro East has a paved loop drive, and a variety of trails of varying difficulty.
Saguaro West is comprised of mostly un-paved roads and trails.
5700 North Sabino Canyon Road. This canyon has a shuttle that will drive you up through the canyon, as well as hiking trails. During and after the monsoons (around August), you can swim in the swimming holes which are an easy mile hike from the parking lot.
This is my favorite picnic area in Saguaro National Park West. It is a remote area on unpaved roads.
