DC Cruises showcases the capital from an uncommon angle: the waterfront. Sightseeing boats available for private parties ranging from 20 to 100 guests drift on the Potomac from Georgetown to the river basin, taking in views of the Kennedy Center, the Lincoln Memorial, the Jefferson Memorial, and the Washington Monument. Daytime excursions grant an unusual view of the monuments from behind, whereas sunset excursions cast the buildings against colorful skies. At night, the moon glows on the marble structures, giving them new mystique. Wine cruises and crab feasts combine on-the-water sightseeing with local fare, and cherry-blossom cruises showcase signs of spring: trees dotted with pink blooms and newborn bills cooing in their bassinets on the mall.
