Oyster Harbors: The Definitive 2026 Guide to Cape Cod's Premier Private Island
When discerning buyers ask me about the absolute pinnacle of luxury living on Cape Cod, there is only one answer: Oyster Harbors. As your trusted luxury real estate advisor, I invite you to explore why this gated sanctuary on Grand Island remains the most coveted address in New England.
Why Oyster Harbors Stands Apart
Nestled on Grand Island and completely surrounded by the pristine waters of North Bay, West Bay, the Seapuit River, and Cotuit Bay, Oyster Harbors offers a level of seclusion that is impossible to replicate. With only one guarded entrance and approximately 400 meticulously maintained homes, this community ensures the high-level privacy that today’s elite buyers demand.
- Restricted Access: A private, 24/7 guarded gate ensures total island security.
- Deep-Water Access: Bridge-free navigation directly into Nantucket Sound.
- Maritime Heritage: A rich history dating back to the Wampanoag tribe and legends of Captain Kidd’s buried treasure.
- Village Proximity: Just 2.5 miles from the high-end boutiques and dining of Osterville Village.
