About North

Riverside

North Riverside, located between Riverside Avenue and the Mianus River, is a residential and commuter-friendly Greenwich neighborhood with leafy streets and a waterfront edge. The neighborhood’s character concentrates around the Riverside Avenue corridor near Riverside Station, where coffee counters, small markets, and service storefronts set a steady weekday rhythm. Architectural cues lean toward classic New England colonials and mid-century splits, with pockets of newer builds tucked behind mature trees. The Mianus River Park shoreline and trails shape daily routines with salt-marsh views and quiet boardwalk moments. Riverside Yacht Club and the Greenwich Audubon Center act as local pillars for on-the-water culture and nature programming. Metro-North service keeps the pace connected while the river landscape keeps it grounded.
