Koko Crater Botanical Garden

Free

Explore rare dryland plants inside Oahu's serene volcanic Koko Crater.

Nestled within the 200-acre basin of Koko Crater, this free self-guided botanical garden features dryland plants from around the world, including cacti, succulents, plumerias, and native Hawaiian flora. A dirt walking loop winds through the quiet crater floor, offering unique botanical displays surrounded by dramatic volcanic walls. Visitors can enjoy a peaceful, scenic walk filled with desert landscapes, vibrant flora, and local birdlife.

Quick tip: Bring plenty of water, a hat, and sunscreen, as shade is minimal and conditions inside the crater get very hot.
