The tourist epicentre of Warsaw is the Royal Route, which runs between the New and Old Towns. The city also has more than it's fair share of green spaces, which really come into their own during the summer months when a variety of concerts and outdoor cafes are on offer.
Warsaw has some excellent museums, including the National Museum, Centre for Contemporary Art and the Warsaw Uprising Museum. The summer months see numerous Festivals taking place, such as the Film festival, Summer Jazz days and the Old-Polish Music festival. Touring the amazing Old Town is essential, fully rebuilt after World War II; it contains the impressive Royal Castle.
