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.
Day 04-05 : Trekking to Namche / Acclimatization rest day.
Day 06 : Trek to Kumjung.
Day 07-08 : Trekking up the Gokyo Valley and enjoy views of massive Cho Oyu.
Day 09-10 : Climb Gokyo Ri / savour the stunning looks of Mt. Everest and pristine lakes.
Day 11 : Trekking on the moraines of the Ngozumpa Glacier to Thangna.
Day 12-13 : Cross the challenging Chola pass and trek to Lobuche: enjoy the superb beauty of Nature.
Day 14 : Trekking Kala Pathar for views across Khumbu Glacier to Everest.
Day 15 : Exploration to the Everest Base Camp.
Day 16-18 : Trekking down to Lukla to end the Everest circuit trek via Pheriche, Thyangboche.
Day 19 : Himalayan flight back to Kathmandu / Rest day.
Day 20 : Free day in Kathmandu.
Day 21 : Trip ends / Airport transfer.(...)"
Thanks
Phil
