Hey NWPhil, are you planning on day hikes from Kathmandu/Pokhara or are you going on a trek to Everest or Annapurna base camp? This will make a huge difference in how you approach this.
Send me some details on your itinerary.
Don't have one yet, per say.
We are going to do our very own itinerary as we go - well, whithin limits, as it will be only me and my wife, aside porters and guide.
The idea is to go from Lukla to Gokyo lakes area, and then cross to EBC, finalizing at start point. Looking at 21 days plus - meaning that, the usual 21 day trek includes about 5-6 days in Kathamandu and Lukla, for aclimatization and tours.
We might add up that to the 21 days of trekking, but not sure yet
see standard hik itinerary below:
Day 01 : Arrive Kathmandu / dinner with cultural program.
Day 02 : Explore Boudhnath and Pashupatinath / Trip preparation.
Day 03 : Fly to Lukla and start Everest trekking.
