Fodor's Review

You can reach Yellowstone's largest hot spring, 370 feet in diameter, by following the boardwalk. The spring, in the Midway Geyser Basin, is deep blue in color, with yellow and orange rings formed by bacteria that give it the effect of a prism. For a stunning perspective, look down on it from the Fairy Falls Trail.
