Does the bus pass that comes with the World Heritage Pass for Nikko & two shrines and a temple get you to Lake Chuzenji and Kegon Falls, or do we have to buy another bus pass to get there?The World Heritage Pass is only valid between the Nikko Stations and the shrines, but not between the shrines and Lake Chuzenji. You have to pay separately for that.
