About Three Mile Bay
Three Mile Bay is a quiet waterfront community along the shores of Chaumont Bay in western Jefferson County. Located right on Route 12E, it offers a peaceful rural setting with easy drives to Cape Vincent and Watertown. The area is a favorite for boaters and anglers, with sheltered bay waters that provide quick access out to Lake Ontario and the broader Thousand Islands region.
Day-to-day life here is low-key and centered around the outdoors, supported by local staples like a post office, a volunteer fire department, and a public boat launch. Students attend Lyme Central School in neighboring Chaumont, just a few minutes down the road, which also serves as the local hub for dining and errands. It is an appealing spot for anyone looking for simple lakeside living with a friendly, small-town pace.
