Jackie O's Private Beach Is Open to All. But It's a Hike.

More than 330 acres in Aquinnah, Martha’s Vineyard—once private land owned by Jacqueline Kennedy Onassis and her daughter Caroline Kennedy—opened to the public last year as the Squibnocket Pond Reservation. The reserve, formerly Red Gate Farm, now offers two trail access points and a secluded swimming beach, plus a woodland walk and routes that reach a half-mile-long shore and a new summer trail along Squibnocket Pond. Parking is limited to 10 south-entrance spots per day in summer and requires online reservations; cellphone service is sparse, and ticks are present. It’s about a 25-minute walk to the ocean. Next year, the land groups plan kayaks for the pond.
