Lake Ronkonkoma NY Homes for Sale

Lake Ronkonkoma’s evolution was boosted in the late 1890s when it started attracting visitors who heard allegations of the healing powers of its lake’s waters. The area changed from residential into commercial, and Lake Ronkonkoma became a resort town. The lake was a great natural resource that supported the area’s economy and brought work and money for many years until World War II, after which the resort business slowed down and many of the summer cottages and bungalows were converted into year-round single-family homes.

Local Area Information

Lake Ronkonkoma is an unincorporated community and census-designated place (CDP) in Suffolk County, Long Island, New York. It bestrides the townships of Smithtown in the west and Brookhaven in the east.

On the Town of Smithtown side, the hamlet is bounded by the unincorporated neighborhood of Nesconset to the northwest. In Brookhaven, its neighbors include the village of Lake Grove to the north, Centereach to the northeast, and Holbrook to the southeast. The rest is bounded by the unincorporated community of Ronkonkoma in the Town of Islip.

The hamlet surrounds a big part of the body of water also called Lake Ronkonkoma, the largest freshwater lake on Long Island and whose shore is nearby several waterfront properties. The lake was once considered sacred and believed to be bottomless by the Native American Indians who utilized its resources. It was also a major factor in shaping the lands around it into what they are today, including Lake Ronkonkoma. The lake is now steeped in lore with a number of different versions, many times involving the “Lady of the Lake.”

Besides the single-family homes, the area also includes multifamily residences, some of which are rentals. Most sections use the Lake Ronkonkoma, NY 11779 ZIP code, while the rest use either 11767, 11755, or 11720.

Most areas in Lake Ronkonkoma are patrolled by Suffolk County Police Department’s 4th Precinct, while the 6th Precinct covers a smaller eastern part.

The area is linked to the Long Island Rail Road network via the Ronkonkoma Station, which is the western terminal of the Greenport Branch and the eastern terminal of the Ronkonkoma Branch. Manhattan, roughly 53 miles to the west, can be reached by car in roughly an hour and 20 minutes to an hour and 41 minutes via the Long Island Expressway or Northern State Parkway.

Lily Pond County Park is a relatively little-known 90-acre hiking park that is also known as the Diane Spitz Memorial Preserve. “Lily Pond” gets its name from its main attraction, a pond filled with lily pads, where fishing and kayaking may be enjoyed. Running parallel to the pond is a 0.6-kilometer loop trail for hiking and observing nature, including the broad range of bird species that inhabit the preserve.
