This is a unique tropical nature preserve and sanctuary. The Garden displays a vast variety of palms, heliconias, gingers, bromeliads, and hundreds of other rare and exotic plants from all parts of the tropical world - presently more than 2,000 species.

Prior to entering the Garden, visitors must register in the gift shop. Across the street is the entrance gate to the Garden. Here you are greeted by the Garden's volunteer gate keepers who will answer your questions and provide free umbrellas in case of rain---take one even if it's not raining when you start your tour! A 500 foot long elevated boardwalk winds down the steep-walled, narrow ravine of Kahalii Stream that now runs dry because a 1949 landslide diverted all its water into Onomea Stream. The Kahalii ravine is filled with exotic tropical growth of giant bamboo, bananas, flowering vines, orchids and ferns. The Garden is home to nearly 200 species of palms: fan, fish-tail, sago, date, and betel nut palms are just a few that can be seen from the Palm Vista. Along the Palm Vista Trail, from the Fern Circle to the bottom of the steps near the Palm Jungle, you will see more than 50 species of plants and trees - including the giant jackfruit tree with its enormous colorful fruit, sometimes more than two feet long! Onomea Falls is set amidst the natural forest of palms and ferns. Exotic mosses grow on the surrounding rocks and trees. Small fish and prawns thrive in the clear, cool water. Just past the falls is Heliconia Trail where more than 80 different plant species grow. The plants range from 2 to 20 feet high. A short ways from here is the Orchid Garden. Nearby, is a small pond which is home to a family of pink Lesser flamingos and Mandarin ducks. Bromeliad Hill is on the Outer Lake Trail and is covered with a vast variety of bromeliads. Then comes VISTA POINT, where you can sit and watch the ocean's pounding waves. The path will continue along the ocean for awhile before coming to Alakahi ("Little River") Stream Trail. Along the Alakahi Stream Trail, there are more than 33 varieties of plants. Soon you'll come to LILY LAKE with it's 110 species of plants and koi fish. Cook Pine Trail is where a 160 feet tall pine is, making it the largest specimen in the islands. You can also see the Bird Aviaries , Torch Ginger Forest, and Giant Fern Circle.
