The vacation center and heart of the Thousand Islands area, Alexandria Bay sits at the edge of the St. Lawrence River. In the late 1800s the village was a popular vacation spot and steamboat stop, attracting wealthy visitors who built homes on the islands. Today Alexandria Bay caters to visitors who want a quick look at the islands, and restaurants and motels abound. The centerpiece is Boldt Castle, on Heart Island, across
from the village. Wellesley Island is home to a couple of state parks and to a cottage community called Thousand Islands Park.
