Any suggested highlights?
Try to be in Namache on a Saturday morning for the weekly market. Go to morning prayers at the Monastery in Tengboche. Spin every prayer wheel you pass. Climb Kala Patar. Stop and talk to the children, take their pictures and show it back to them. Ask adults if you can take their picture. If you have time visit Goyko and Chhukhung. Take 10 times more pictures than you think you should. Walk slow and enjoy each moment! You can read about my trek for my experience.
