ALOHA FROM JENNIE: On our Media Videos page, we bring to you some of our favorite sights and sounds from Oahu hiking trails, such as the Halona blowhole and Nuuanu valley waterfalls. A well reviewed site by visitors and locals alike is the Koko Creater Botanical Garden which stretches for sixty acres inside an extinct volcano.
Admission is free and consists of a two mile looping trail which takes you through natural locales. The popular plumeria grove showcases many varieties of this very fragrant blossom, which is often used to make flower leis. The aroma therapy plus bougainvillea and other colorful bushes add to this relaxing and pleasant starting area of one's hike.
Another noteworthy area is the desert cacti, which flourishes in the dry climate of the crater. Some of the specimens are large in size, and visitors enjoy taking photos standing next to them for proportional reference.
The environment is conducive to bird watching, since the greenery attracts quite a bit of wildlife. There are over 200 specimens of trees, such as wiliwili, koa and kiawe. Most travelers find Koko Crater gardens a pleasant way to pass a few hours on a sedentary nature hike/walk with a wide array of interesting subjects to take in.
