The 10 Best Attractions in Washington, DC

The domed home of the U.S. Congress atop Capitol Hill, one of the most recognizable buildings in America, with a Rotunda ringed by historic paintings and the marble National Statuary Hall. Free guided tours start from the underground Visitor Center; book ahead and clear airport-style security. To watch Congress in session you need a separate gallery pass from your representative's office.

America's most hallowed military cemetery, just across the Potomac, where more than 400,000 service members and their families are buried on rolling hillsides. Do not miss the Tomb of the Unknown Soldier changing of the guard, the Kennedy gravesites and eternal flame, and Arlington House above. Entry is free, but the grounds are vast, so consider the paid tram or plan a lot of uphill walking, and keep a quiet, respectful demeanor.

One of the most powerful and rigorously designed museums in the world, this institution documents the Holocaust through artifacts, testimony, and immersive architecture that itself conveys unease and weight. The permanent exhibition on floors 2-4 takes 2-3 hours and is not suitable for young children. Timed passes are required for the permanent exhibition and should be reserved in advance online. Emotionally demanding but essential — locals consider it among the most important sites in the city.

The official residence and workplace of the U.S. president, an instantly recognizable neoclassical mansion best photographed from Lafayette Square to the north or the Ellipse to the south. Self-guided interior tours are possible but must be requested months ahead through your member of Congress or your embassy. Most visitors simply view the exterior through the fence and stop at the nearby Visitor Center.

A striking Tidal Basin memorial where a 30-foot likeness of Dr. King emerges from the Stone of Hope, backed by a curved wall inscribed with his quotations. It is the first Mall memorial dedicated to an African American and to a non-president, and it carries real emotional weight. Free and open around the clock; pair it with the nearby FDR and Jefferson memorials on a Tidal Basin loop.

A domed, Pantheon-inspired rotunda on the Tidal Basin honoring the third president, with a bronze Jefferson statue ringed by his own writings. It is a bit removed from the main Mall cluster, best reached on a walk around the Tidal Basin, and spectacular when the cherry blossoms bloom. Open 24 hours and free, with fine sunset views back toward the city.

A stunning 10-acre formal garden tucked behind a Federal-style mansion in upper Georgetown, designed over decades by Beatrix Farrand and considered one of the finest garden designs in North America. Spring cherry blossoms and wisteria are extraordinary, but the garden is beautiful in every season. The attached museum houses a world-class Byzantine and Pre-Columbian art collection and is separately free. Admission to the garden is charged seasonally; check hours carefully as they vary.

Sharing a stunning Greek Revival building with the American Art Museum, the Portrait Gallery holds the only complete collection of presidential portraits outside the White House, plus compelling galleries on American history through portraiture. The Robert Longo and Kehinde Wiley Obama portrait has become a genuine cultural touchstone. The central Kogod Courtyard — a glass-canopied atrium — is one of the most beautiful public spaces in DC and a perfect lunch stop. Far less crowded than the Mall museums and easy to combine with Penn Quarter dining.

The Smithsonian's National Zoo is a legitimate world-class facility spread across 163 hilly acres in Rock Creek Park, home to giant pandas, Asian elephants, and hundreds of other species. The Asia Trail and American Trail are the strongest sections. It's genuinely free to enter though parking costs money — take the Metro to Woodley Park instead. The terrain is hilly and the full loop is several miles, so wear comfortable shoes.

Housed in one of DC's most spectacular interiors — a massive Victorian brick hall with 75-foot Corinthian columns — this museum covers architecture, design, engineering, and urbanism in genuinely engaging ways. The Great Hall alone is worth the visit and has hosted presidential inaugural balls. Rotating exhibitions are consistently thoughtful and well-designed. It's often overlooked by tourists, making it a reliably uncrowded respite from the Mall.
