The Fish River Canyon 5 day trek is one of the best in the world.
But it’s very difficult to get a reservation, even a year in advance. I’ve been turned down for all dates in June 2015. 😦
But I may try to show up at the trailhead anyway. Hang out. And look to substitute for a hiker missing from a booked group. (You must have a minimum of 3 people to register, in any case.)
Wish me luck.
I’ve put up a draft information page on the Fish River Canyon trek with what I was able to find out online.
