These impressive Grade 6 rapids are massive they have been kayaked and you can find an impressive Youtube video of an Alexandra farmer who went both down and up them in jet boat and proceeded to then cop a $1500 fine for doing so, but what thrill!
The Rapids sit below the famous Nevis Bluff which had a massive collapse in September 2000 blocking the road into Queenstown from this direction for weeks. A lot of that material ended up in the river making the rapids even more spectacular.
