This picture is a sample of the many Big Island waterfalls that visitors get to enjoy on this tour.  A van will take you UP-RIVER  from the visitor center through a pasture gate a short distance and let you enjoy many waterfalls and view a one of a kind scene where the River hits some steep rapids  down a natural flume and then goes underground through a Lava Tube and pours out 30 feet later as a nice waterfall. We need small groups of 6-16 to do this tour.  Call 808-930-9477 for pricing and availability.
