The Koko Crater Botanical Garden certainly has an interesting location going for it. Situated literally in the crater of this last active Oahu volcano, the currently 60 acre facility has an additional one-hundred and forty acres of land to grow into. The entire 200 acre area was set aside in 1958 to provide a place for Hawaii's endangered plant life to thrive. Though not fully developed yet, there are still many beautiful examples of the what it will one day host. A variety of flowering trees and plants are already spreading sweet smells across this scenic area. Visitors who undertake the grueling Koko Head railroad trail will notice the botanical garden off in the distance. Like all of Hawaii's botanical gardens, the unique flora here makes visiting and touring the area much more exciting than you might expect a simple garden stroll to be.
