Waterfall Tours & Adventures on the Big Island of Hawaii

The Big Island's windward coast receives over 200 inches of rain annually, feeding hundreds of waterfalls that cascade through lush tropical valleys, dense rainforest, and volcanic rock formations. From easily accessible roadside falls to hidden cascades deep in the jungle, the Big Island offers waterfall experiences for every adventure level.

Guided waterfall tours range from comfortable van tours along the scenic Hamakua Coast — stopping at Akaka Falls, Rainbow Falls, and Umauma Falls — to adventurous hiking tours that lead to secluded waterfalls with natural swimming pools. For the ultimate thrill, waterfall rappelling tours let you descend directly down the face of a cascading waterfall on rope.

The Hamakua Coast between Hilo and Waipio Valley is the island's waterfall heartland, with dozens of falls visible from the road and many more accessible by short trails. The Hilo area is home to the iconic Rainbow Falls (Waianuenue) where morning mist creates rainbows in the spray, and Akaka Falls which plunges 442 feet through a tropical gorge.

Van tours from the Kona side combine waterfall stops with other attractions — tropical gardens, small towns, and scenic overlooks — making them an excellent full-day experience for those staying on the island's western coast.
