The Kreeger Museum: The Kreeger is one of the most beautiful museums in Washington. Its collection includes important Impressionists and members of the Washington Color School, and displays of African, Asian and pre-Columbian art. The Kreeger, which reopened April 1, welcomes visitors to its galleries for four 50-minute timed-entry slots per day, beginning at 10 a.m., 11 a.m., 2 p.m. and 3 p.m., and limiting capacity to no more than 15 people per hour. When the 50 minutes are up, visitors are directed outside to the sculpture garden, which includes works of art along a wooded trail. Visitors who don’t wish to spend time indoors are allowed to proceed directly to the sculpture garden. Open Tuesday to Saturday. Suggested donation $10 adults, $8 students, military and seniors.
