If you live in Massapequa, your July calendar probably splits along an invisible line. North of Merrick Road, the summer belongs to the Town of Oyster Bay: the pool at Marjorie R. Post, the concert lawn at John J. Burns, the ball fields, the ice rink turned dry. South of Merrick, the calendar is quieter on paper and busier in practice, because it runs through two private waterfront clubs that most maps never mention.
The claim of this piece is simple. For the peninsulas that hang off the south end of town, Biltmore Beach Club and Harbour Green Shore Club do the work a village green does elsewhere. They are the reason a Friday in Biltmore Shores looks nothing like a Friday in North Massapequa, even though both households pay taxes to the same town. Once you see the rhythm, the rest of a Massapequa summer week falls into place.
Two clubs, two peninsulas, one weekly rhythm
Biltmore Beach Club sits at 185 Biltmore Boulevard, on the bay side of Biltmore Shores. Located on the south shore of Long Island overlooking South Oyster Bay, it occupies over three acres of waterfront property, offering a 1,000-foot bayfront beach, an Olympic-size swimming pool, and a 100-slip marina. It is a private members-only club, with facilities that include a swimming pool, boating activities, and an active social calendar for members and their families. That last phrase does a lot of work in a resident's life. It is why a Biltmore Shores address tends to come with a familiar answer to "what are you doing this weekend?"
Harbour Green Shore Club plays the same role a mile east, at the tip of the Harbour Green peninsula. The unique community of some 400 homes is located on the tip of a peninsula overlooking the Great South Bay, and the Club offers members an Olympic-size pool, a lovely beach area comprising three acres of prime beachfront property, and a private marina located at the foot of the Grand Lagoon. Established in 1957, HGSC is the heart of the social activity in the community. Read that sentence twice. The club is not an amenity attached to the neighborhood. The neighborhood is arranged around the club.
The two clubs run on different membership models, which is one of those quiet local mechanics that shapes who ends up living where. Harbour Green's beach club is unusual on Long Island in that it is open to residents with no strict residency requirement, while Biltmore Shores enforces one — to use the Biltmore Shores beach club you generally have to live in the Biltmore Shores area. If you have wondered why buyers looking at Bar Harbour or Nassau Shores sometimes drift toward Harbour Green during their search, that is part of the answer.
What the summer calendar actually looks like at the clubs
The social calendars are members-first, but a handful of the summer's set pieces spill out into the public conversation through pop-ups and touring acts. A few worth knowing, whether you belong or you have a friend who does:
- Friday, July 17, 2026: Grooving at Biltmore Beach Club, 7 p.m. The mid-July anchor on the Biltmore social calendar this year, at 185 Biltmore Boulevard.
- Saturday, July 11, 2026: TCB at Biltmore Beach Club, 2 p.m. A daytime event on the club's summer lineup, per the club's public listing on allevents.
- Friday, June 19, 2026: Cousins Maine Lobster at Harbour Green Shore Club, 5 p.m. The traveling lobster roll truck pulled up to 38 Riviera Drive East for an early-summer opener at HGSC.
None of these are destination events for someone driving in from off the peninsula. They are neighborhood events that happen to have out-of-town names attached, and they explain why a Friday evening in Harbour Green in June smells like drawn butter.
What Merrick Road does for the rest of us
Cross back over Merrick and the town takes over. The two big Town of Oyster Bay parks sit within a mile of each other on the north side of the road, and between them they hold whatever the shore clubs don't.
Marjorie R. Post Community Park is the one people forget to brag about. Marjorie R. Post Park is unique in that it has an ice-skating rink and an Olympic size pool, located on Unqua and Merrick Roads, with tennis courts, paddle board courts and much more. In July it is essentially the town swim club for households that do not have a private one, and the pool complex is what fills the weekday afternoons that the clubs down south fill privately. The park then flips into a second identity in the fall. The Family Fall & Halloween Festival at Marjorie R. Post lands on Saturday, October 24, 2026, from 1 to 4 p.m., with a u-pick pumpkin patch, hayrides, refreshments, inflatables, games and more, and families are encouraged to attend in costume. If you are new to the neighborhood, that afternoon is the one to circle. It is how you meet everyone who has been living three blocks over for a decade.
John J. Burns Town Park, just west, is the concert park. The Music Under the Stars series runs at 8 p.m. on various dates in July and August, presenting three weekly concerts over six weeks throughout the Town of Oyster Bay. Burns holds the Massapequa dates. It is worth checking the Town's Cultural and Performing Arts calendar before you plan a mid-week dinner in July, because on concert nights the parking pattern on Merrick reshuffles for two or three hours. Locals who know the schedule leave early or eat late.
There is one more Burns date that matters for anyone who owns a dog on this side of town. DogFest Long Island is happening on Saturday, October 10, 2026, from 11:00 a.m. at Marjorie Post Park. It runs at Post rather than Burns, and if the last two years are any signal, the Unqua Road side of the park fills first.
Why any of this matters if you already own here
Three practical takeaways for the people who already live in Massapequa and are just trying to plan a summer.
The first is that the peninsula neighborhoods and the north-of-Merrick neighborhoods run on genuinely different infrastructure. If you live in Bar Harbour, Biltmore Shores, Nassau Shores, or Harbour Green, your weekend is oriented around water and a club, and your inland options are a bonus. If you live in North Massapequa or East Lake, your weekend is oriented around the town park system, and a day at the bay is a project. Either can be a great summer. They are not the same summer.
The second is that the club calendars leak. If you are not a member, you are not shut out of the whole thing. The touring food trucks and tribute acts booked at Biltmore and HGSC are public in the sense that they get listed on general event platforms, and the parking around 185 Biltmore Boulevard and along Riviera Drive East on those Friday evenings is a decent tell for what is going on. If you have friends who belong, this is the summer to accept the invitation you keep dodging.
The third is that the Town's fall pivot happens sooner than most people plan for. Marjorie Post switches into pumpkin-patch mode in late October, and by early November the same park is preparing for ice. The Holiday Experience at Marjorie R. Post arrives in December 2026 with festive lighting displays, winter sing-a-longs, giveaways and appearances from visitors from both Arendelle and the North Pole. If you have children in the house, that six-week window between the Halloween Festival and the Holiday Experience is the busiest stretch of the park's year, and it starts eleven weeks from now. Book the babysitters early.
The bay does not know any of this. It will keep doing what it does at the south end of Riviera Drive East and at the foot of the Grand Lagoon, whether the club opens its gate or not. But the two clubs are the reason the south end of Massapequa feels like its own small town within the larger one, and the two parks up on Merrick are the reason the rest of Massapequa does too. Knowing where the seams run is most of what it means to actually live here.
If you are thinking about a move between these two versions of Massapequa, or from outside the area into one of them, that geography is worth a conversation before you tour a single house.
