Myself and a couple of mates have just got back from spending 4 weeks in Nepal, where we completed the 3 Passes Trek in the Sagarmatha NP. It was completely different to tassie walking yet it was an amazing trip. I really have Nick S to thank for the inspiration for the trip, leading up to summer my mates and I couldnt decide on which Tas walk to do and then Nick posted his trip report on the 3 passes and so I thought why on earth are we arguing about WA's vs Spires when we could be doing this, and finally we agreed.
I wont go over the details to much as we basically followed the same itinerary as Nick. Highlights for me were the acclimatisation circuit around Namche, Chukkung Ri, watching the sun rise over Mt Everest from Kala Pattar, and the last few days from Dzongola to Namche particularly Renjo La.
