Our acclimatization trek was 3 days in the Crocker Ranges. It was tough. It is called World Challenge for a reason, It was hot, humid, steep and muddy and we got torrential rain every afternoon. Add in the challenges of sleeping in jungle hammocks, cooking on open fires in very wet conditions, carrying heavy packs etc. Everyone was challenged, everyone had to dig deep at different times, everyone had to support each other, and everyone came through and everyone made it to the end!!!!There was a lot of well earned pride in the group and a great sense of personal achievement after the trek.
