The problem with museum hopping is the "hopping" part. In bigger cities, you can spend as much time going to and from museums as you do looking at exhibits. For convenience's sake, catch some of Boise's finest museums all at once on International Museum Day, which is Sunday, May 22. Held at the Old Idaho State Penitentiary, Museum Day let's you see exhibits courtesy of the Idaho Museum of Mining and Geology, the World Center for Birds of Prey, the MK Nature Center, the Idaho Military History Museum, the Boise Art Museum and more. Learn to pan for gold, meet awesome birds and try out cultural activities courtesy of the Idaho Black History and Basque museums. Learn about plants at the Idaho Botanical Garden and prisoners at the Old Idaho Pen.
