The impression of walking up to the world's 6th-largest cathedral, a hulking mass cut over a period of 83 years of 150,000 tons of stone, is alone worth the trip. Tours are a must if you really want to see the cathedral, and the towers and the crypt are off limits without a guide during the busy season. The organ demonstrations are spectacular and loud. Check the website for events, as there is often children's programming as well as major concerts.
The Cathedral Church of Saint Peter and Saint Paul in the City and Episcopal Diocese of Washington, commonly known as Washington National Cathedral or National Cathedral, is a cathedral of the Episcopal Church. It is located in Washington, D.C., the capital of the United States. It was begun in 1907 and formally completed in 1990. It is of Neo-Gothic design closely modeled on English Gothic style of the late fourteenth century and is the second-largest church building in the United States, and the third-tallest building in Washington, D.C. The cathedral is the seat of both the presiding bishop of the Episcopal Church and the bishop of the Episcopal Diocese of Washington. Over 270,000 people visit the structure annually.

A collection of 400 species, including 2,000 animals. Get a map at the entrance, take your time, and be prepared to walk a great deal. Bring water—the concessions here are insultingly expensive. The most crowded exhibits are nearly always the Pandas and the Ape House. The pandas are perhaps the zoo's shyest residents. The Ape House is fun no matter the crowds. Other hits include the Seals & Sea Lions Exhibit, the Reptile House, the remarkable Aviary, and the irresistibly cute prairie dogs.
Little known even to locals is this private house-museum with an impressive collection of paintings by the impressionist and early modern masters. The house itself is a work of art, designed by modernist architects Philip Johnson and Richard Foster.

Friendship Park
Turtle Park has the coolest playground in town. The centerpiece is an enormous sandbox littered with eminently climbable turtle sculptures and plastic shovels and buckets. In the summer, you can get the sand off your kids away without a trip to the bathrooms at the "sprayground." The park is fenced in and has plenty of shade, as well as four baseball fields, two basketball courts, two tennis courts, and a rec center.
A hidden gem of magnificent proportions. Marjorie Merriweather Post, prominent businesswoman and heiress to the Post Cereal fortune, fashioned her estate next to Rock Creek Park to be an extraordinarily stately and luxurious site for entertaining guests, housing her impressive art collections, and with the intention of leaving it behind for the world to enjoy. The mansion is a treasure trove of French and Russian decorative arts, much of which she obtained from the USSR, whose government under Stalin was then auctioning off a good portion of its cultural heritage to finance its war efforts. Second in grandeur only to the art collection itself are the French and Japanese-style gardens—great places to linger long after the tour.
