Martha’s Vineyard is synonymous with family fun in the sand and surf, but New England’s largest island is much more than that. It’s a fisherman’s paradise. From Gay Head to Cape Poge, striped bass, bluefish, false albacore, and bonito are seldom more than a long cast away, and the swimming, bicycling, and beachcombing will have your spouse forgiving the fact that a surf rod is your constant companion. To escape the tony tourists that crowd the island during peak summer, buy an over-sand vehicle permit, which opens up miles of lonely beaches. 508-693-0085; www.mvy.com.
