Koko Crater Botanical Garden, Honolulu

4.1
#21 of 51 in Parks in Honolulu
In 1958, 200 acres on the slopes and basin of Koko Crater at the eastern end of Oahu were set aside as a botanical garden. Although it is still only partially developed, long-range plans envision Koko Crater Botanical Garden as an example of a xeriscape. Here selective planting and water conservation techniques transform this landscape into a garden where plants suitable to these desert-like surroundings can thrive and flourish.

  • Beautiful Botanical Garden, one can visit during tough dangerous hike to Koko Head, it has very good collection of botanical species, I was there in November 2017, regarding Koko Head Hike, only physically fit & healthy person must try, it's a practical TMT test, I was enjoyed the hike & views from the top view points on 10th Nov 2017, few photos clicked are attached here rest detailed all photos uploaded separately, enjoy
  • The walk up Koko Crater is NO JOKE. Prepare yourself with heaps of water and snacks for energy, probably in a backpack as I was crawling up on all fours by the time we reached the top. This hike is steep in parts, but the stairs are good and there was a constant stream of people going up when we were there. The view from the top is magnificent, however I would only recommend doing this hike if you're feeling well as I was a little under the weather and didn't enjoy the rewards of the hike as much as I should have!
  • A wide variety of interesting trees and plants from all over the world in the bottom of an Hawaiian crater. Well labeled and unique.
  • Wow, amazing diversity of plants. Trails are a bit rough and it's tough to look where you're going with so many beautiful plants everywhere
  • It was okay. It's not the good season for most flowers, and the trail needs some TLC- litter such as a cigarette butt and old battery on the ground...malama ka'aina please. Enjoyed having the trail to ourselves- very hilly so wear good shoes. Nice but has the potential to be magnificent with a bit more TLC. 🌿
