Nestled on 6.5 PRIVATE ACRES along a stunning peninsula, 30 Black Horse Lane in Cohasset is a rare waterfront estate offering over 1,400 feet of direct Gulph River frontage with private dock. This 7-bedroom, 7.5-bath residence has been beautifully updated, seamlessly blending timeless charm w/modern amenities. The expansive grounds showcase stone terraces, rolling lawns, granite outcroppings, mature trees and private escape areas through the woods to enjoy the serenity of this magical site. Resort-like amenities include a heated pool and spa with pool house and bath, custom tennis court and a private dock with easy harbor access, and a newly renovated Boat house. A four-car garage w/guest quarters above adds flexibility for family and guests. Despite its quiet seclusion, this coastal haven is just a short stroll to downtown Cohasset and the harbor, and 45 minutes to Boston by car, train, or boat. One of Cohasset’s PREMIER ESTATES, a perfect blend of luxury, nature, and convenience.
