The 584-acre park began with an initial land purchase by the State of Vermont in 1975. It is named for Niquette Bay, the local name for an indentation along the northeastern shore of Lake Champlains larger Malletts Bay. 4700 feet of scenic rocky and sandy shoreline along the bay comprise the park's southern boundary.

The property, much of it farmed and pastured through the 1800s, is today predominately forested. Two long ridges with summits rising to over 400' elevation run parallel along either side of a flat, sandy terrace bisecting the property. This terrace, in turn, is bisected by a brook and associated ravine. This brook, over 1000s of years, has carried away sand and silt as the ravine was carved, depositing it into Lake Champlain and forming the sandy but shallow beach along the eastern half of the park's shoreline.

The westerly half of the park shore is of dramatically different character. Here, sheer cliffs of dolomitic limestone rise abruptly from deep water to heights exceeding 60 feet. These cliffs form the headwall of the western ridge that cuts through the park.
