The park's famous Waterfall Trail is uniquely accessible: its first 0.5 miles to the Petroglyph Plaza is a barrier-free, hard-packed paved walkway engineered for strollers and wheelchairs. Along this barrier-free section, children can marvel at hundreds of authentic petroglyphs carved into dark basalt rock faces by the prehistoric Hohokam culture over 1,000 years ago. Beyond Petroglyph Plaza, the final 0.4 miles to the waterfall pool becomes a rugged, rocky desert wash best explored on foot or with a toddler carrier. Visit the park Nature Center for children's desert library books and animal exhibits. ## Similar picks in Phoenix - [Tiny Art Show — White Tank Library, Waddell](https://grassyknees.com/phoenix/activities/tiny-art-show-white-tank-library-waddell--listing-d39bb0b5ada4821fca8e57f2) — Nov 2 – Nov 16 · White Tank Library, Waddell · All ages · checked Oct 30.
