Gorak Shep is located at 5140m above sea level and is the highest camp on this trek. It often gets quite cold at night at around -23. It certainly felt like that in our bedroom.
Everything froze that night! Our toothpaste, water and even our wet wipes.
It was also a scary process going to the washroom. It was a drop toilet, and the ground around it was frozen and very slippy!
The thought of going there in the middle of the night, using my headlamp, was enough to make me stop drinking liquids at 5:30pm!!
I survived the night!
