Washington, DC is the capital of the United States, and as such, it offers many points of interest of governmental and historical value. DC is home to several iconic landmarks, including the White House where the U.S. president resides, the Capitol building that houses the meeting chambers of the Senate and the House of Representatives, and the National Mall, where you can stop by the Lincoln Memorial, the Washington Monument, and the World War II Memorial. One of the reasons Washington, DC is among the best destinations to visit with your family is because it is home to so many world-famous museums, including the Smithsonians – 16 museums scattered across the District, most of which are open every day of the week, and even better, every single one is free.
D.C. is not just about politics and museums, though. The city’s active nightlife fittingly ranks it among the biggest party hubs in the country. Head to the vibrant Dupont Circle neighborhood to check out some of the finest restaurants that the nation’s capital has to offer, or join a food tour of Georgetown to get a taste of the area’s culture along with its cuisine.
