Most visitors head to Provo , which receives nearly all of the country's international flights and has the major hotels and restaurants. Even if you plan to stay there, however, you should consider excursions to one or more other islands. Particularly recommended are Grand Turk , a terminally calm, easy-going place and just a thirty-minute flight away, notable for its great colonial architecture, the National Museum and more fantastic diving and beaches - or a boat trip around the spectacular Caicos Cays to Middle or North Caicos , where you can check out some dramatic caves or the remains of an old plantation house.
