More than 20,000 years ago, the grounds of Mercy by the Sea—indeed all of Connecticut and Long Island Sound—were covered in ice more than a mile deep! The movement and melting that glacial ice formed the Sound and deposited the large boulders that dot both the beach and landscape. Thousands of years of wave action deposited the sand along the shoreline, creating the Sound’s beaches, of which Mercy by the Sea’s is but one.

The beach is not only a relaxing refuge to read, gaze out at the water or track the flight of birds but also a lovely area to stroll or collect shells. Mercy by the Sea values stillness, silence and solitude, and we ask that all guests respect this quiet and reflective atmosphere. Please note that Mercy by the Sea's beach is private and reserved exclusively for the use of registered Mercy by the Sea guests

For guests who do have access, please note, we do not allow smoking, alcoholic beverages, loud music, fires or grilling on the beach. There are no lifeguards, so swimming is at your own risk. Children under 18 are not allowed to use the beach or to swim. We ask that you wear appropriate beach attire and refrain from entering the house in beachwear.
