Langston Golf Course in Washington DC has a rather curious layout. The 9th hole green is by the clubhouse, you walk pass that to get to the first hole. After you are done on 9, you walk again past the first hole, past the practice area, past the 18th green, over a river (they sometimes have you tee off on 10 on the near side of the river, if you play from the tips), to the 10th hole. Then the course plays up, back over the river (on a par 3), and down to the 18th, where you have to walk back to the clubhouse. If the clubhouse were located where the current practice area was, the course would look like a normal American two-looper (except for the fact that the driving range is past the 18th hole), but because the clubhouse is actually off to one end, it has a weird lack of continuity, particularly the walk from 9 to 10.
Other than the (reasonable) walk from the clubhouse to the first, and the somewhat less reasonable walks from the 9th to the 10th and the 18th back to the clubhouse, the course is a very easy walk.
