I've lived in Phoenix for years and never actually hiked around here before. It was nice though! The buttes and beautiful. It's very busy since its in the middle of the city but you can go off trail on some areas and you'll never get lost. Not a hard hike at all, but it would be really great for getting a good run workout in! Loved the rock stairs and it's fun to climb around the buttes too if you want some incline. I'll definitely go back for a workout since its so conveniently located. Just for reference, it's across the road from the gardens and zoo, not on the same side. The directions on here will lead you right to the trailhead.
Arid! May be life bird for many, high above the butte are white throated swifts. They just look small and black. You feet will like an upgrade from sneakers to hiking shoes, see loop trail photos. Great views of Tempe and Scottsdale. Easy 1 hour walk.
