The heads at the Knysna entrance are world renowned for their difficulty. Wind direction, swell, and requirements for timing the entrance with the tide mean that many sailors can’t make the entrance and bypass Knysna. We got in easily but when we went to leave a thick fog had settled and we weren’t sure we could get out. The fog started to lift and we made a run for it, easily making it out to continue down the South African coast to Cape Town.
