Once part of the 18th-century farm of royal Governor Benning Wentworth, this coastal hideaway borders the shoreline of tidal Sagamore Creek. You’ll find remnants of the old estate, including Creek Farm Cottage built in 1887 now used by the Shoals Marine Lab for research. The short trail around the property follows the shoreline past a canoe/kayak launch and a constructed tidal pool. At low tide, you can walk across the connecting strip of land to Goose Island. If you come to paddle, haul your craft across the lawn to the put-in, then head left toward Portsmouth harbor for views of the Wentworth Coolidge Mansion and Wentworth by the Sea Hotel. Or go up Sagamore Creek and stop by BG’s Boat House for a lobster roll.
