Koko Crater Botanical Garden


About Koko Crater Botanical Garden


Located within the landmark Koko Crater on the eastern side of Oahu is the Koko Crater Botanical Garden, a 60-acre basin inside of Koko Crater, where you’ll also find the Koko Crater Trail.

The botanical garden’s two-mile loop trail leads visitors on a one-hour self-guided tour through varieties of dry land, desert-like plant collections from Hawaii and other parts of the world. Youll see endangered plants from the Americas, Hawaii, Madagascar, the Pacific, and Africa. Along the trail, naturalized kiawe and koa haole trees dominate the landscape.

Entry is free and parking is free. The botanical garden is open daily from sunrise to sunset (9am – 4pm), and closed on Christmas Day (December 25) and New Year’s Day (January 1).

Be prepared: wear comfortable walking shoes, as surfaces along the trail include loose rocks and slippery surfaces. Never handle any plants in the botanical garden. Bring water.

Plants you’ll see:

  • Baobab trees (Africa)
  • Dragon’s Blood Tree (Africa)
  • Hawaiian Gardenia
  • Yucca tree (Americas)
  • Sonoran Palmetto (Dry Land Palms)
  • Henna shrub (Africa/Middle East)
  • Red Ilima (Hawaii)


In 1958, 200 acres inside the Koko Crater were reserved for the development of a botanical garden, as part of the Honolulu Botanical Gardens project. Today, the Koko Crater Botanical Garden is 60 acres large, and the remaining 140 acres are yet to be developed as originally planned. Thus, some visitor facilities have yet to be constructed.
