Portsmouth, located on the South coast of England, is home to several important historical dockyards and thus a storied maritime heritage. Though many people travel here to experience the nautical atmosphere, Portsmouth also offers many attractions and experiences to suit every taste.
For a taste of the sea, Henry VIII's Mary Rose is a must-see attraction, as well as Lord Nelson's famous HMS Victory. Both ships are accompanied by museums where visitors can learn more about these significant historical warships. If the weather drives you inside, take a walk around the Portsmouth Museum and Art Gallery, hosting a variety of displays and recreations of how life has changed in Portsmouth over the centuries. To see the whole city all at once, climb Spinnaker Tower to see the city from 170 meters high. Finally, if you're feeling brave, walk across the glass Sky Walk to see the waves crash on the shore beneath your feet.
Due to its many ports, Portsmouth is accessible via ferry, as well as train, car, and bus. The South Western Railway makes getting to Portsmouth from London and other southern towns easy, while National Express and Megabus provide bus services that link many other major towns and cities.
