Fodor's Expert Review Royal Navy Submarine Museum
Here you can learn about submarine history and the rigors of life below the waves with the help of family-friendly interactive games. The highlight is a tour of the only surviving World War II submarines in the United Kingdom, the HMS Alliance and the midget-class HMS X24, from the cramped living quarters to the engine rooms. Also on the large site is the first Royal Navy sub, Holland 1, built in 1901, and a Biber, a German WWII midget submarine. From Portsmouth Harbour, take the ferry to Gosport and walk along Millennium Promenade past the huge sundial clock. From April to October, an hourly free water bus runs from the Historic Dockyard.
