We have reached Dingboche (4,400 m) after 2 hectic days of trekking. The altitude is starting to slow us down. Each step takes a lot of effort and shortage of breath is becoming the norm. We are now at the snow line and night time temperatures are now about -15 C. Thank goodness we have top quality down sleeping bags and jackets. We stayed at Tengbouche on the way. It is renowned for its very famous temple which was beautiful to see. But just as much interest to us was Lavazza coffee and French pastries. In the middle of nowhere who would have thought. We saw a shop sign offering oxygen and helicopter evacuations. A little confronting. The views of the surrounding mountains en-route have been simply stunning. What has surprised us that in a country that is the 22nd poorest in the world we can still access the Internet and a mobile phone network. All the locals despite there very modest means have mobile phones. We are off to Labouche tomorrow which is another 500m higher but much closer to our final destination.
