This enormous entertainment, education, and sports center on the east bank of the river is bursting with activities and has been popular since it opened in 2001. For kids, its hands-on science center -- W5 -- is a hypermodern, interactive learning environment where children can compose their own music on an air harp, create tornadoes, learn how robots are built, and try to make one of their own. Also in the complex are an arena where the Belfast Giants ice hockey team plays, an IMAX cinema, video-game arcades, and lots of bars, restaurants, and cafes. On a rainy day, there's probably no better place to go to keep everyone amused and dry.
