Boise

Boise is the capital city of Idaho. The Boise River Greenbelt is a series of tree-dotted trails and parks hugging the water's edge. In an art deco building, downtown's Boise Art Museum has contemporary works and an outdoor sculpture garden. The grand, sandstone Idaho State Capitol Building is nearby. The Old Idaho Penitentiary contains 19th-century prison cells and gallows, plus historic military weaponry.
