About Flea Markets in Lake Ronkonkoma

Lake Ronkonkoma has a small but charming flea market scene — just one dedicated spot in the directory, but it’s the kind of place that punches well above its weight. Jay’s Hidden Treasures Flea Market & Gift Shop is an indoor, owner-operated shop stocked with antiques, vintage finds, and collectibles, making it a solid option whether you’re a serious picker or just browsing on a whim. Being indoors means it’s a reliable destination regardless of Long Island’s weather, and parking is available on site.

Jay’s Hidden Treasures is the standout name in Lake Ronkonkoma’s flea market scene, and with 90 reviews it’s clearly found a loyal following. Shoppers consistently call out the sheer variety — “tons of stuff” is a phrase that comes up more than once — and the reasonable prices make it easy to leave with something you didn’t expect to find. The personal touch matters here too: reviewers specifically mention the owner Jay and his mother as friendly and helpful, which gives the place a welcoming, neighborhood feel that bigger markets often lack.

If you’re planning a visit, note that Jay’s is closed Mondays and Tuesdays and opens at noon Wednesday through Sunday, with a slightly later closing time on Fridays (until 7PM) — making Friday afternoon a good window if you want a bit more time to dig through the inventory. Go in with an open mind; the “hidden treasures” name is apt, and the experience is very much a hunt.
