I have just been reminded that this trek is soon to begin again for 2011. I believe it is an experience of a lifetime.
Check it out on their site. “The Great New Zealand Trek”
It is all for a good cause as well as the great experience.
You may not be able to make it this year but keep a spot in your diary for next year. I am going to try to get to NZ to do the trek next year. Tough but will be fun I am sure.
