Big Bus Tours Washington D.C., Washington

Three separate tour loops give patrons of Big Bus Tours a chance to see as many of D.C.'s incredible sights as their minds can handle—and there's plenty of fresh air thrown in for free. Hop-on, hop-off privileges give visitors to the city (or residents looking at it with new eyes) a chance to pop out to see the Lincoln Memorial, then re-board at their convenience to journey toward one of the other beautiful, historic marble landmarks that dot the city. But you don't have to leave the bus to enjoy the sunshine: the double-decker tops offers riders the chance to slap on some sunscreen, grab their shades, and feel the wind blow through their hair as softly as it laced through President Washington's straw-filled ponytail.
