About Hay Island

HAY ISLAND: Breathtaking, unobstructed views of the Long Island Sound stretch from this private island at the end of a gated causeway on Darien's cherished waterfront coast. Held by one family for over a century, this waterfront sanctuary features a meticulously crafted 8,684 SF New England colonial built in 2010. Positioned high above the water, with sweeping southeasterly views the six-bedroom, seven-bathroom main house is adorned with exquisite millwork, high-end finishes, and six fireplaces. An infinity-edge pool overlooks one of two sandy beaches and the glittering waves, with the historic Greens Ledge Lighthouse in the distance. The island also includes a two-bedroom guest house, a pool house equipped with a kitchenette and full bathroom, a dock, separate spa and a freshwater pond.
