I'm planning a return to the Khumbu in a year or two and am wondering why more people don't trek via Phortse instead of Tengboche on the way to EBC Kala Patthar? I had to abort my trek in December 2019 due to heavy snow (December is the driest month, right?), so I have already visited Tengboche and am looking for more adventurous options... On the map, it looks like the climb from Phortse Tenga to Phortse is roughly 200m (3810-3610m) versus the 610m climb from Phunki Tenga to Tengboche (3860-3250m) - so there's much less elevation loss on the Phortse route, which would seem to make it more desirable. What are the reasons that the Phortse route is less popular? Is it all about visiting the monastery or are there other reasons? Is Namche - Phortse doable in one day (looks similar to Tengboche on paper)? Thanks for any help.
