Ronkonkoma Beach Access provides public entry to Lake Ronkonkoma, Long Island's largest freshwater lake, with a DEC-maintained angler parking area and concrete boat ramp located off Victory Drive on the west side of the lake.

The site is always open for boat launching and fishing at no cost, with electric trolling motors permitted (gas motors prohibited).

An accessible 100-foot fishing pier is also available nearby in the Suffolk County Park off Shore Road on the north end of the lake, though seasonal parking fees may apply.
