5. Lost City GC, South Africa

The 13th hole here is utterly mental. Miss the green to the left and your ball will enter the crocodile pit. The ‘croc pit’ is some 10-12ft below and there are signs saying it is ‘prohibited’ to enter it to retrieve your ball. You’re also not allowed to ‘throw objects’ at the crocs. That just makes them angry. You can collect your ball if you want, but only if you want to die a very painful death.
