Urban Dunes

About

Urban Dunes at 122 East 91st Street on the Upper East Side is NYC's only indoor sandbox playground designed for kids 9 and under. The space offers three themed sandboxes — Dino Dig, Golden Beach, and Construction Zone — housed in a converted UES townhome. Sessions are 90 minutes at $30 per child, with staff raking the sandpits daily and sanitizing toys. The natural-sand experience differentiates Urban Dunes from typical NYC indoor playgrounds and gives parents an alternative to public-park sandboxes (often shared with wildlife). Strong fit for UES families wanting hygienic sensory-play experience for toddlers and elementary-age kids. Booking is by website inquiry; popular weekend slots fill quickly so advance reservation is recommended.
