    Living in Mount Sinai

    Mount Sinai is defined by its harbor, where Cedar Beach, the marina and Satterly Landing draw boaters, swimmers and walkers along the Sound. The Mount Sinai school district is a major draw for families, and Route 25A connects the hamlet to neighboring Port Jefferson and the wider North Shore corridor.

    Housing is largely post-war ranches and colonials plus newer subdivisions on the wooded ridges above the harbor, with a handful of homes enjoying water views. There is no LIRR station in the hamlet; commuters use the Port Jefferson Branch from adjacent Port Jefferson, a diesel line usually requiring a transfer at Huntington into the city.
