What you see is what you get here. Given the extreme temperatures and rugged landscape, it's quite a thrill to see how far you can be pushed and how much you're willing to take.
Take my word for it though - you'll be surprised by how tough you can be when situation calls for it! :)
Goecha La isn't a teahouse trek. You'll need a porter and guide and will have to carry all your equipment and requirements from Yuksom itself, nothing will be available on the way. Here's the sherpa I went with - Norbu: +91 70763 41507. I would highly recommend him.
