"Off-Roading on Nantucket's Isolated Beaches Nearly half of Nantucket is open space and conservation land. Much of the island remains undiscovered unless you brave the isolated beaches and go off-roading. If deflating your tires and conquering sand trails sounds intimidating, instead explore the 16 miles of trails in the Coskata-Coatue Wildlife Refuge with a Conservation Foundation tour. Admire the dunes, coastal forests, and tidal ponds in one of the most isolated parts of the island. At the very tip of the elbow, you’ll be rewarded with Great Point Lighthouse (a.k.a. Nantucket Lighthouse) and views of seals frolicking in the waves. Families with picnics and fishermen looking for bluefish will line part of the beach, but this remote area feels private and removed from the hustle of the summer season elsewhere on the island."
