About Oyster

Bay

Oyster Bay, located between Cold Spring Harbor and Bayville, is a waterfront and historic Glen Cove neighborhood with a working harbor and leafy, estate-era streetscapes. The neighborhood’s character concentrates around Audrey Avenue at Spring Street, where coffee counters, independent boutiques, and old-school storefronts set a walkable, small-town cadence. The Oyster Bay Railroad Museum, the Oyster Bay Historical Society’s Earle-Wightman House, and the Planting Fields Arboretum State Historic Park act as cultural anchors. Shingle-style homes and classic Colonials mix with village-era cottages near the shore. Waterfront paths and marinas frame daily routines with salt-air views. Beaches and preserves shape the landscape from cove to bluff.
