Hey... I'm not sure if my experience is gonna help all that much, you probably aren't going to be travelling in quite the same way that I did when I did my trekking (admittedly, mine was only in the Hindu Kush, the foothills to the foothills of the Himalayas - still pretty high though) I mean, we kinda cheated by using porters and a guide and stuff. Speaking of which, do be sure that you know exactly where you're going etc.

But stay safe, and watch out for the wind - we had our loo-tent blown away down a valley at one point. Do be sure to bring along a little more than the basics - it's the small things that make camping on some windswept mountainside more homely.

And, most importantly, have fun.
