Washington

The must-see attractions include the White House, the Capitol Building, the National Mall (with the Lincoln Memorial, Washington Monument, and World War II Memorial), the Smithsonian museums (National Air and Space Museum, National Museum of Natural History, etc.), and the National Gallery of Art.

The best way to get around Washington is by using the Metro (subway), which is efficient and covers a large area of the city. Walking is also a great option, especially in the National Mall area. Ride-sharing services and taxis are readily available as well.

The best time to visit Washington is during the spring (April-May) and fall (September-October) when the weather is pleasant, and the crowds are smaller. The summer months can be hot and humid, while winter can bring cold temperatures and occasional snow.
