Lukla - a seven hour journey from Namche - can be done in one day without too much difficulty as much of the walk is flat or down hill - though remember that the final hour or so entails a steep climb up to the airstrip.
Khumjung - a good one hour walk.
Tengboche - a five to six hour journey - the first part is pretty flat, but there is a steep and long hill up to the monastery.
Thame - a three hour walk - mostly flat after the climb out of Namche. Exit by trail in front of Namche Monastery.
