Experience the Big Island's tropical splendors on a drive along the scenic coastline. Visit Akaka Falls, Mauna Loa Macadamia Nut Farm and the Pana'ewa Rainforest Gardens & Zoo on this half-day excursion. At Akaka Falls, take in the breathtaking views as the cascade of water plunges 442 feet over a volcanic ledge framed by rainforest. A one-mile stepped-path leads through the lush tropical forest to the Akaka Falls Lookout. Next visit the Mauna Loa Macadamia Nut Farm where macadamia nuts are processed and packaged. Browse the gift store for souvenirs and sample some nuts. Travel to the 12-acre Panaewa Rainforest Gardens & Zoo; the only tropical rainforest botanical garden and zoo in the United States. It is home to more than 100 varieties of palms, orchids, bamboo and tropical plants as well as animal species including the endangered Nene (Hawaii State Bird).
