Just north of Hilo is one of the largest botanical gardens in Hawaii, with some 5,000 species. Although it no longer offers a vista of spectacular, triple-stacked Umauma Falls (see below), it still lays claim to a huge children’s maze (second in size only to Dole Plantation’s on Oahu), a tropical fruit arboretum, ethnobotanical and wellness gardens, and flower-lined walks. Waterfall lovers will be heartened to note that the owners have also created a road and trail leading to viewing areas above and below the previously hidden 100-foot Kamaee Falls ($6 if you want to go there only), as well as a trail leading past a series of shorter, bubbling cascades in Hanapueo Stream. If that’s just too peaceful for you, opt for one of the Segway tours, ranging from 30 minutes to 3 hours ($57–$187) or a zipline tour ($167), which like guided walks should be reserved in advance. All tour rates include garden admission.
