Rub elbows with the rich and famous along this wide, white-sand beach, a true Hamptons treasure. A stroll along Coopers Beach offers the unique view of a seemingly endless Atlantic on one side and historic mansions on the other. Ideal for families, the gently sloping beach has lifeguards, a snack bar, chair and umbrella rentals, and a summer concert series. Allow time for shopping in town on quaint, tree-lined streets like Jobs Lane. Parking is pricey and can be tight, so arrive early.
