To trek in Nepal is to walk and walk and walk some more and to walk all uphill. It means you stop only to eat lunch and maybe catch your breath. If you want to take photos and I mean good photos it means you will be the very last of your group to get to the next guest house and this will happen every day. It means you will spend time all by yourself unless you have a guide with you who wonders (but never says it) if you will ever get to the guest house before it gets dark. Nepal is all uphill—for every foot you take downhill you will have to regain that ground sooner or later so be prepared to go up and up and up day after day. But also be prepared for scenery you will see nowhere else in the world. It is unique and spectacular. Worth every step.
