Lake Ronkonkoma's rich history as a summer resort destination in the early 1900s centers around its namesake lake - the largest freshwater lake on Long Island. This Suffolk County hamlet uniquely spans three towns — Brookhaven, Smithtown, and Islip — creating a distinctive community where suburban neighborhoods meet natural landscapes. Housing options range from historic converted summer cottages that recall the area's resort past to contemporary townhomes and apartment communities.

The 243-acre lake remains the community's centerpiece, with the Lt. Michael P. Murphy Memorial Park providing swimming access and lakeside recreation during summer months. The commercial district along Portion Road includes Lake Shore Plaza and numerous local businesses. The area's geography has shaped its development, with neighborhoods radiating outward from the lake's shores, each offering its own perspective of this natural landmark.

Commuters benefit from Lake Ronkonkoma's strategic location in Suffolk County, with quick access to both the Long Island Expressway and Sunrise Highway. The Lake Ronkonkoma LIRR station serves residents with rail service to Manhattan in approximately 90 minutes. The proximity to Stony Brook University Hospital and other mid-island business centers provides diverse employment opportunities. One-bedroom apartments rent for around $2,200 monthly, making the area a cost-effective alternative to western Suffolk and Nassau County locations.
