When you’re contemplating the waves as they crash on to the shore it can be difficult to remember that Long Island is a part of New York city. This exciting island is a favourite with surfers and beach lovers, and lies in the Atlantic ocean to the east of New York Harbour.
Thanks to good transport links, you can reach Long Island from any other part of the US, and international flights make getting to the beach from further afield relatively simple. The beaches of Long Island sound are fabulous, and fans of ‘The Great Gatsby’ will adore the North Shore.
