The actual Dupont Circle, around which the neighborhood is centered, has a nice park in the middle of the traffic circle. It's a favorite neighborhood spot to read, play chess, and people-watch. On summer weekends there are relatively frequent musical performances. Otherwise, the neighborhood is not brimming with activities kids will likely hate it here. If you are feeling understimulated, hop on the Red Line and go one station north to get to the Zoo in Woodley Park.
