The bay is oriented northeast from the river, which it joins at the head of
Long Reach, just south of the village of
Evandale. Belleisle Bay forms part of the northern boundary of southern New Brunswick's "Kingston Peninsula", with the southern boundary being the
Kennebecasis River. Belleisle Bay has little current as it has few freshwater inlets and acts more-or-less as a lake in a glacial valley, framed by the low rolling hills of the
St. Croix Highlands of the
Appalachian range. Although the bay is mostly freshwater, the entire lower Saint John River system has a limited saltwater tidal influence resulting from the
Reversing Falls. Its waters freeze completely in the winter months. Measuring approximately 18 kilometers long by 1 kilometer wide, Belleisle Bay has several small freshwater streams, namely
Kingston Creek, near the mouth of the bay, and
Belleisle Creek at the head of the bay. A small
wetland also exists at the head of the bay. The bay hosts a single island,
Ghost Island, located between
Elmhurst and
Lower Kars. The bay is located entirely within
Kings County. The
Belleisle Bay Ferry, a year-round
cable ferry, crosses the bay between
Earle Wharf and
Long Point. ==See also==
