Enjoy swimming in crystal clear glacial ponds? Manaquayak Preserve and Seth’s Pond are also less than ten minutes’ walk from the house. Manaquayak Preserve is one of the newest Martha’s Vineyard Land Bank properties. This twelve-acre property contains a pristine, glacier-formed kettle pond originally called Ice House Pond. It has only four parking spaces to limit its use. Seth’s Pond has a sandy beach and is popular with young children.
