Milford-on-Sea is famous for its seafront views of the Isle of Wight, its seafood restaurants and most of all the stunning nature reserve and stone causeway out to Hurst Castle. The causeway is a mile and a half out into the Solent with the nature reserve on the inland side and the deep waters on the other. During the warmer months, the castle is open to the public and is home to a museum and a café. The castle was built for Henry VIII as part of his sea defences. After a stroll out there, you can catch a ferry back from to Keyhaven, a short walk away from Milford-on-Sea.
