The privately owned/open to the public park has a 25-foot waterfall, ample multi-level seating, and thanks to trees and the neighboring buildings - its almost always shady (and cool!). With a cafe onsite, its the perfect place to grab a bite. As the waterfall is tucked away and not easily visible from the street, its a fun surprise for little ones to learn of this “secret” waterfall in the city. WHEN: ⏰Open daily 8am - 8pm
