The Sands Point Preserve is on the original Guggenheim Estate. It embodies the grandeur and elegance that define the Gold Coast period of the early 20th century, when prominent American families built great mansions on large estates as summer retreats along the Long Island Sound. The Sands Point peninsula was the famed “East Egg” in F. Scott Fitzgerald’s “The Great Gatsby.” Hours: 9:00 am – 5:00 pm Admissions: $15 per car
