The city of Portsmouth may be better known as a sea port than a central hub for people moving by land around England, but the Hard Interchange in the city offers travelers a busy bus station. Services to and from Portsmouth's Hard Interchange are operated by National Express and Megabus, with both offering services inland to London and onwards to the rest of England. First and Stagecoach South also operate buses around Portsmouth from the same bus station. Megabus offers a limited number of services from Portsmouth, which tend to be to destinations in London and destinations in the English Midlands such as Birmingham. National Express offers a more substantial range of options for those entering Portsmouth by bus, with services running from London and nearby Bristol. Other connections include a service from Birkenhead and one from the Yorkshire city of Bradford.
The historic dockside sits just a short walk from The Hard Interchange, which is named after the area of beach with hard enough ground for sailors to moor their boats on. Many visitors arrive in Portsmouth with the long history of maritime achievement on their minds, with the historic Mary Rose and HMS Victory housed in a dry dock in the city. When hunting down the local nightlife and shopping options, Gunwharf Quays is always a popular option with the newly constructed Spinnaker Tower the centre piece of the new development. Music has always played a big part in the history of the city, from the sea shanties sung by sailors to the many established music venues that can be found, which includes the iconic Wedgewood Rooms. Sports fans can spend some time enjoying professional football at the historic Fratton Park ground that was opened in 1898 with its world famous mock Tudor entrance.
