See Niagara Falls by day and by night on this two-day small-group trip from Washington, D.C. Drive north through the countryside to the falls, where you’ll take in Horseshoe Falls, American Falls, and Bridal Veil Falls from a range of viewpoints. Add the optional Classic Tour for Whirlpool Park, the thundering Cave of the Winds, and the famous Maid of the Mist boat ride, then head out after dark for the illuminated night tour, when the falls glow under colored lights. The next day brings an optional stop at the world-renowned Corning Museum of Glass before the comfortable ride back to D.C. With a bilingual driver-guide and a night right at the falls, it’s an unforgettable way to experience one of the world’s great natural wonders.
