>>1391429Booked through an agency when we were in Kathmandu, haggled a bit in person, I believe we paid ~650USD per person - probably about as cheap as it gets. Off season in December, two people (one will cost more), walked up to the last village before BC by ourselves without guide or porter (took 7 days, including 3 acclimatization days - count 20-30USD per day). Mandatory guide, permit, etc included. You'll also need a plane ticket from Kathmandu to Lukla (forgot exact price, but it's fixed at ~160USD?), which is faster and cheaper than taking a bus but having to hike more than a week extra.
So you're looking at ~1000USD plus flight to Nepal and back under ideal circumstances. Would consider hiring a porter next time though, we did the whole Three Passes Trek with me playing photography pack mule and I lost weight like crazy - 6kg in 17 days.
