Top Landmarks in Shirley

Shirley, New York, sits on the South Shore of Long Island in Suffolk County, and its most notable landmarks reflect that setting: a stretch of barrier-island coastline, tidal rivers, and a historic estate connected to the nation's founding. For a broader overview of what the area offers, the Shirley Travel Guide: Things to Do, Landmarks, Food, and Itineraries is a useful starting point before diving into the specifics below.

The William Floyd Estate

The best-known landmark associated with Shirley is the William Floyd Estate, also called the Old Mastic House. This property was the longtime home of William Floyd, one of the signers of the Declaration of Independence, and it remained in the Floyd family for generations. The estate is administered by the National Park Service as part of Fire Island National Seashore, even though it sits on the mainland rather than on the barrier island itself. Visitors commonly walk the grounds, view the historic house and outbuildings, and take in the surrounding fields and family cemetery. Because operating details for National Park Service sites can change seasonally, it's worth checking the official Fire Island National Seashore website for current visiting information before planning a trip.

Smith Point County Park and Fire Island National Seashore

A short distance from the William Floyd Estate, Smith Point County Park marks the eastern gateway to Fire Island National Seashore. This is where the mainland connects to the barrier island by bridge, making it a natural access point for beachgoers and for those interested in the seashore's dune and maritime environments. The Fire Island National Seashore's Wilderness Visitor Center is located near this end of the park, and it serves as a starting point for exploring the roadless wilderness area that stretches along the island. The park and seashore together are commonly visited for beach walking, birdwatching, and views of the Atlantic coastline, and their proximity to Shirley makes them easy to reach from anywhere in town. As with any coastal or federally managed site, hours, fees, and access can vary seasonally, so conditions, access points, and seasonal programming are best confirmed through the official National Park Service or Suffolk County parks pages.

Southaven County Park and the Carmans River

North of the more developed parts of Shirley, the Carmans River winds through Southaven County Park, a wooded, riverside space that contrasts with the coastal landscape to the south. The park is a popular spot for freshwater fishing, canoeing and kayaking, and walking trails that follow the river corridor. As with Smith Point, hours, fees, and access at this Suffolk County park can vary by season, so it's worth checking current park information before a visit. While less widely known outside the region than the William Floyd Estate or Smith Point, Southaven County Park is a well-established recreational landmark for residents of Shirley and neighboring communities, and it reflects the ecological range of this part of Long Island — from tidal wetlands near the shore to freshwater river habitat further inland.

How the Landmarks Cluster Geographically

One helpful way to think about Shirley's landmarks is in terms of a north-south line. The William Floyd Estate and Smith Point County Park sit close together near the southern edge of town, both accessible via the William Floyd Parkway corridor, which runs through Shirley from the Long Island Expressway down toward the coast. This makes it possible to visit the estate and then continue a short drive to the park and seashore entrance in the same outing. Southaven County Park, by contrast, lies further north and is better treated as a separate stop, particularly for visitors more interested in river-based activities than beach access.

Combining Landmarks Into a Walk or Day Trip

Because the William Floyd Estate and Smith Point County Park are close to one another, they pair naturally as a half-day itinerary: a walk through the estate grounds followed by time at the park and seashore entrance. Comfortable walking shoes are worth packing, since both the estate grounds and the seashore trails involve uneven or sandy terrain. Ordinary urban-and-outdoor awareness applies at the beach and wilderness areas — checking tide and weather conditions, staying on marked paths, and being mindful of sun and insect exposure are all reasonable precautions for a coastal visit.

For a more structured plan, the Shirley 1-Day Itinerary lays out a sample schedule that incorporates these landmarks, while the Shirley 3-Day Itinerary offers a longer framework that also folds in Southaven County Park and other nearby recreation areas.

Practical Notes for Visitors

Shirley is a residential community of roughly 27,800 residents as of the 2024 ACS 5-year estimates, and its landmarks are generally treated as day-use destinations rather than tourist hubs with extensive visitor infrastructure. That means dining options near the estate and park are limited compared to more built-up areas, so many visitors plan a meal in town before or after landmark visits — the Where to Eat in Shirley guide offers an overview of local options. Because outdoor sites like Smith Point and Southaven are more enjoyable in favorable weather, it's also worth reviewing the Best Time to Visit Shirley page when planning a trip. For other logistical questions, including transit and general trip planning, the Shirley FAQ covers commonly asked questions.

Taken together, these sites give visitors a sense of both the historical and natural character of Shirley: a coastal community shaped by its Revolutionary-era history at the William Floyd Estate and by its ongoing relationship with the Atlantic shoreline and inland waterways at Smith Point and Southaven County Park.
