Known also as Long Beach Bay, Hallock Bay is roughly 680 acres with low water depth. It's an estuary off Gardiners Bay, separated by a thin stretch of land called, Long Beach. It is a marshy area, hence the low depth of the harbor. There is a sense of seclusion due to it's branched location from the rest of the state. From a small beach, there is easy access to the water (parking nearby). Contact Orient Beach State Park for parking and entrance fee information.
