Riverside, NY (CDP)

Riverside sits along the south bank of the Peconic River in the Town of Southampton, placing it right at the gateway to Long Island's East End. Located directly across the water from downtown Riverhead, the hamlet gives residents easy access to nearby restaurants, grocery stores, and waterfront entertainment while keeping everyday life relaxed and low-key. The community centers around a convenient road hub that connects Route 24 and Flanders Road, making it a handy starting point whether you are commuting west or heading out toward the beaches and vineyards on either fork.

Nature is a big part of living here, with thousands of acres of protected parkland bordering the neighborhood. The vast David A. Sarnoff Pine Barrens Preserve and the trails at Cranberry Bog Nature Preserve sit right at the edge of town, offering great spots for hiking, trail running, and birding. With modest housing options, scenic river access, and ongoing community revitalization efforts along the waterfront, Riverside offers a practical and grounded alternative for people looking to settle in Southampton.
