Pima County Extension

The Rillito River has paths for biking and walking (and horseback riding and…) along most of both its sides in the Tucson area. Though there are benches and shady spots, a special spot is southeast of the junction with Campbell Avenue: the gardens (and more) at Pima County Extension:

Pose as farmers or veggies (I added the red arrows)... though I'm not sure if selfie sticks work here:

You'll find benches and picnic tables among the gardens:

Last but not least, there's a tile mural near the entrance. Click there to see it on the Tucson Murals Project blog. I took the photos during one of the twice-monthly Saturday morning tours May 14th.

You can read more about the gardens, and one of the Saturday tours, in the Arizona Daily Star article Tucson's hidden glorious gardens are open to all.

Location: Entrance is east of Campbell, across the street from the Trader Joe's parking lost.

Parking: Limited. The parking lot for the Rillito River trail is nearby. You might try the parking lot at the shopping center's parking lot — or walk along the river from one of the other spots.

Hours:The office is open 7:30-4:30 weekdays. After 5pm the gate to the parking lot may be closed, and you can park in the Rillito lot… but it may not be safe (there have been break-ins). The office (and parking lot) are are also open some Saturday meetings.
