In 1958, Koko Crater on the eastern side of Oahu was set aside for development into a botanical garden. Today, it is a free botanical garden that features sixty acres of unique plants located in the middle of the 200-acre Koko Crater. The garden is known for its cultivation of dry land plants, and its xeriscape landscaping allows them to grow plants in this dry landscape and let them flourish.
If you are planning to visit the garden, please remember to bring water. The paths around the garden will take you around a 2 mile loops that are rocky and uneven so its a good idea to bring walking shoes.
