A difficult 10.5km hike starting at Injisuthi Camp to Centenary Hut but worth every aching muscle once you get to the top. The first 7.5 km's are easy and then the "little" hill to climb up to the hut. It seems never ending at times but is most definitely achievable by most people, take it easy up the hill and you will be at the hut in no time at all.
The views are stunning. The hut itself is in a state of disrepair so take along a tent unless you like sleeping in a hut without windows and springs for a mattress.
