Cherry Grove, a tiny hamlet on Fire Island’s barrier beach, and Mount Sinai, a North Shore harbor community on Long Island’s mainland, represent two radically different approaches to New York coastal living. Cherry Grove is legendary — a historic LGBTQ+ vacation community known for its beaches, nightlife, and the famous Miss Fire Island Pageant. Mount Sinai is a family-friendly suburb with year-round schools, services, and infrastructure. Comparing them is less about ‘better or worse’ and more about understanding what each offers and who they serve.Cherry Grove’s real estate market is tiny and seasonal. With only a few hundred houses in the hamlet, inventory is extremely limited. A charming cottage three houses off the beach sold for $920,000 in February 2025 (Summer Place Realty/Fire Island News). Prices for Fire Island properties generally range from $337,500 for vacant land to $2 million+ for oceanfront homes. Cherry Grove is part of the Town of Brookhaven in Suffolk County — the same township that includes Mount Sinai — but the two communities could not be more different in character.

Cherry Grove properties are accessed exclusively by ferry (from Sayville) or private water taxi. There are no cars on Fire Island — residents walk, bike, or use small wagons to transport goods. This car-free lifestyle is part of the charm, but it also means that year-round living requires significant planning and adaptation.
2. The History & Culture of Cherry Grove
Cherry Grove holds a unique and important place in American cultural history. It has been a haven for LGBTQ+ New Yorkers since the 1930s and 1940s, when artists, writers, and theater performers began summering there to escape the prejudice of mainstream society. The community became one of the first openly gay and lesbian vacation destinations in the United States.The Cherry Grove Community House and Theatre, established in 1948, is one of the oldest continuously operating community theaters in New York. The annual Miss Fire Island Pageant — a beloved drag competition — has been a cultural institution for decades. Artists and writers including W.H. Auden, Christopher Isherwood, and Patricia Highsmith are among the luminaries who have spent time on Fire Island.The entire Fire Island community was designated a National Seashore in 1964, preserving its pristine beaches and maritime forests. The Sunken Forest, a globally rare holly maritime forest, lies just a few communities west of Cherry Grove and is accessible via boardwalk trails.
3. Mount Sinai: Year-Round Coastal Living
While Cherry Grove thrives from May through September, Mount Sinai is a four-season community with full year-round infrastructure: schools, medical facilities (near Stony Brook University Hospital), shopping, dining, and municipal services. The median household income of $111,602 supports a strong local economy anchored by healthcare, education, finance, and professional services.Mount Sinai’s 455-acre harbor — one of the few large, undeveloped embayments remaining on the North Shore — is a designated New York State Significant Coastal Fish and Wildlife Habitat. This ecological distinction gives the community a natural beauty that rivals Fire Island’s beaches, with the added advantage of year-round accessibility and lower insurance costs (no barrier island flood risk).
4. Cost Considerations
Fire Island properties carry unique costs that mainland homes do not: flood insurance premiums are substantial (barrier islands face severe flood risk), ferry costs add up quickly ($20+ round trip per person), and maintaining a home accessible only by water creates logistical challenges for contractors, deliveries, and emergencies.Mount Sinai’s mainland location means standard homeowners insurance, full road access for maintenance and emergencies, and the everyday convenience of supermarkets, gas stations, and medical offices within minutes.
5. Lifestyle Comparison
Cherry Grove is, at its core, a vacation community. The summer season is electric — beach parties, communal barbecues, sunset cocktails on the deck, and a nightlife scene that punches far above its tiny size. The Ice Palace nightclub and Cherry Grove Beach Hotel are legendary gathering spots. For the LGBTQ+ community in particular, Cherry Grove represents a space of freedom, acceptance, and celebration that is deeply meaningful.Mount Sinai offers a different kind of fulfillment: the pleasure of watching your children grow up in a safe, tight-knit community; weeknight dinners at the Heritage Diner; Saturday mornings at Cedar Beach; autumn walks along the North Shore Rail Trail; and the comfort of knowing that your investment in a home is also an investment in a permanent, year-round life.▶ Video: Cherry Grove Fire Island Documentary — Watch on YouTube▶ Video: Fire Island National Seashore Tour — Watch on YouTube

7. Who Should Choose Which?
Cherry Grove is ideal for buyers seeking a vacation home, seasonal retreat, or investment rental property in one of America’s most unique beach communities. It is not practical for families with school-age children or anyone requiring year-round mainland convenience.Mount Sinai is ideal for families, professionals, retirees, and anyone seeking a permanent, year-round home with coastal access, excellent schools, and strong appreciation potential. It offers everything Cherry Grove does not: infrastructure, stability, and the peace of mind that comes with a traditional suburban home purchase.
Conclusion
Cherry Grove and Mount Sinai exist in the same county but in entirely different worlds. One is a summer dream, the other a year-round reality. Both are beautiful. Both are valuable. But for the vast majority of homebuyers, Mount Sinai offers the complete package: beach access, community, schools, and a home that serves you every day of the year.
