Wings and Waves Waterpark

This is really three attractions in one: museums of aviation and space travel, and an IMAX theatre. Howard Hughes' H-4 (HK-1) Flying Boat, better known as the Spruce Goose, is the most well-known, but there are over 60 other aircraft and spacecraft to see. The space museum has a pleasantly even-handed coverage of the international history of space exploration, with unique exhibits such as an ICBM in a simulated silo. There is a good café here. Enough to see that aviation fans will want a whole day.
