Just north of Hilo is one of Hawaii’s largest botanical gardens, with some 5,000 species. Although it no longer offers a vista of spectacular, triple-stacked Umauma Falls, 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, as well as a trail leading past a series of shorter, bubbling cascades in Hanapueo Stream. If that’s just too peaceful for you, there are also Segway excursions ranging from 30 minutes to 3 hours ($57–$147) and a zipline tour ($147), which should be reserved in advance; rates include garden admission.
