Why does a 263-acre county park sitting right off Montauk Highway have a gravel lot that fits about a dozen cars and nothing else? No restrooms. No pavilion. No sign explaining any of it beyond a trail map tacked up at the entrance. Drive past on a Saturday morning and you'd assume it's an afterthought, the parcel nobody got around to developing.
That assumption is backwards. Terrell River County Park's story includes a historic estate, a county purchase, and a later stewardship arrangement.
What's Actually Behind the Gravel Lot
The entrance sits on the south side of Montauk Highway, between Bay and Belleview avenues, directly across from Kaler's Pond Park. If the small lot fills, which happens on weekends, Kaler's Pond is where the overflow parks. From there, a white-blazed loop runs roughly 2.6 to 2.8 miles through wooded interior, salt marsh, and open meadow before reaching a beach that borders Moriches Bay. Suffolk County's own description calls it a park with phenomenal vistas and abundant shore access, and adds a line that tells you everything about how it's run: there are no amenities, and it's a carry-in, carry-out park. You bring your trash back to your car because there's nowhere else for it to go.
Leashed dogs are welcome. There's no entrance fee. And unlike a lot of county parkland that gets a paved lot and a mowed lawn eventually, this one has stayed exactly as undeveloped as it was when the county first took it over.
The House Left, the Land Stayed
The story begins with a family estate. The property was once part of the Havens Estate, land that stretched from the Terrell River to Senix Creek and north toward what's now Sunrise Highway. John H. Havens purchased half of Warretta Neck in 1755, and the Havens family held the land for generations, running it as a working estate with a home, a barn, and outbuildings on the site.
In 1974, Robert H. Pelletreau donated the house to the Moriches Bay Historical Society, which relocated it across the road to where it still stands today as the Havens Homestead museum. The land itself, though, stayed put, no longer tied to a family or a residence, just acreage waiting for its next chapter.
That next chapter arrived in 1986, when Suffolk County purchased the parcel outright.
A Stewardship Arrangement at Terrell River County Park
Buying the land was one decision. What happened next was another. In 2001, the county designated the Moriches Bay Audubon Society as the park's steward. The Audubon Society's nature center sits right at Kaler's Pond, on the opposite side of Montauk Highway from the park entrance, which is why the two properties function almost as one stop even though they're managed differently.
A tenth of a mile away, Flight 800 Memorial Park, close enough to reach on the same outing, has a pond, a well-maintained playground, and picnic-friendly landscaping. Terrell River County Park has salt marsh, maritime forest, and an unpaved trail. The two parks offer different settings.
The park reads less like municipal recreation and more like a nature preserve that happens to be free and open to the public.
What You'll Actually See on the Trail This Fall
The trail itself changes character as you move through it. Near the entrance, the woods run to white oak, prickly ash, and Atlantic white cedar, typical Long Island interior forest. Closer to the beach, the plant life shifts to catbrier, sassafras, and pitch pine, the scrubbier growth that tolerates salt air and sandy soil. The Terrell River runs along the property's eastern edge, flowing north to south into Moriches Bay, and it's more than scenery. The Moriches Bay Audubon Society describes the river as a nursery ground for fish and crustaceans, which is part of why the park draws serious birders and not just casual walkers.
Ospreys nest along the riverbanks and are active fishing and tending young through the warmer months, and the mix of wetland and woodland supports egrets, herons, and owls across the seasons. Fall is a particularly good stretch to catch migrating species moving through, and the Audubon Society has historically organized guided bird walks in the park, taking advantage of terrain that regular visitors already know is some of the better birding ground on this stretch of the South Shore.
At the far end of the loop, the trail opens onto a small beach on Moriches Bay. Visitors who've walked it regularly recommend timing the beach section for low tide, when more shoreline is exposed and the walk out onto the sandy point is easier going.
Before You Go
A handful of practical notes make the difference between a good visit and a frustrating one:
- Parking is limited to a gravel lot at the entrance. If it's full, cross Montauk Highway to Kaler's Pond Park.
- There are no restrooms or trash cans anywhere on the property. Carry out what you bring in.
- Trails can get muddy after rain, and wear that holds up to unpaved, sometimes uneven footing is worth it.
- Tick season runs long on Long Island, and bug spray is worth having regardless of month.
- Low tide gives you more beach to walk at the trail's end, so checking a tide chart before you go is worth the extra minute.
None of that is complicated, but it's also not posted anywhere obvious, which is part of why so many people who've lived in the area for years have never actually walked it.
The Two Stops Make More Sense Together
Because the house and the land were separated back in 1974, visiting one without the other means missing half the story. The Havens Homestead museum, just across Montauk Highway, is where the family's original 1750s home now sits, moved from its original spot on the estate and preserved by the Moriches Bay Historical Society. Walking the trail and then crossing the road to see where the house ended up gives you the full arc: a working estate, a donated house, and acreage that became a county park.
That's a rare thing to find intact this close to Main Street. Most parcels this size, this near a hamlet's commercial core, get subdivided, paved, or landscaped into something tidier. This one didn't. The house was moved in 1974, and the Moriches Bay Audubon Society became the park's steward in 2001.
If you've walked past that gravel lot on Montauk Highway without ever pulling in, this fall is as good a time as any to see what's actually back there. And if the Moriches area's mix of undeveloped shoreline, working waterfront, and small-town Main Street has you thinking more seriously about calling it home, Donna Neyland can walk you through what's actually available on this side of the bay.
