Pull on your life jacket and reef shoes before jumping in the water to float downstream, winding through a limestone gorge overhung with thick vines, fringed ferns and mossy trees. The river flows at a gentle pace, eventually reaching your destination, Mount Hope Waterfall. Here you can climb the falls and take a break halfway as the water runs all around you. This is a far less strenuous but no less exquisite alternative to Millennium Cave, the perfect compromise for those who want an adventure but aren’t ready for the challenge of caving.
