Smithtown Bay is between the entrances to Huntington Harbor on the west and Port Jefferson Harbor on the east. The westernmost part of the bay is the Nissequoque River, and the easternmost part is the entrance to Stony Brook Harbor. Fronting the bay is Governor Alfred E. Smith Sunken Meadow State Park, home to Sunken Meadow Beach.
Beaching your boat at Sunken Meadow is prohibited. In addition, it’s wise to stay a safe distance offshore to avoid contact with swimmers venturing out from the beach.

This wide bay is a good spot to tube or water ski. Don’t count on dropping anchor and floating serenely at all times — if the Long Island Sound is rough, the bay will be, too.

Smithtown Bay has no amenities or facilities. Bring along your own fun and food!
