After a long, cold winter, it's always great to celebrate spring once it's officially sprung. Step aboard one of National Ferry Fleet's luxurious vessels, and set sail on the Potomac, taking in the capital's glorious landmarks and the gorgeous cherry trees -- which, if you're lucky, will be in full bloom. You've only got a limited window of time to soak in the beauty of the blossoms and capture panoramic photos commemorating the occasion, so don't miss this unique way to view one of D.C.'s most popular annual events. During your hour on board, let the wind blow through your hair on an outdoor deck, or relax in the climate-controlled interior cabin, and enjoy snacks and refreshments available for purchase from two onboard bars.
