Join a tour from Luganville and prepare yourself for some hard walking work. Trek and trudge through the jungle, across creeks, along bamboo bridges and through cascades to this massive cave, 20m wide and 50m high. Climb down a bamboo ladder, and through a rocky pool dodging cascades and little bats, then out into the sunlight and into icy water to zap down the rapids on a kids blow-up floaty thingy past amazing towering rocks, gorgeous rainforest and waterfalls. Scramble out all wet and shivery to climb back up to your bus. It’s an awesome experience.
