Frequently Asked Questions
Is the Wai Koa Loop Trail suitable for beginners?
Yes, the trail is generally considered easy to moderate, making it suitable for beginners and a range of fitness levels. Its difficulty comes more from its length than from aggressive terrain or significant elevation changes. It is mostly flat with a wide, unpaved path.
Is this a loop trail or an out-and-back route?
While traditionally known as a loop, some sections may currently be an out-and-back trail. It's best to check local signage or with Anaina Hou Community Park for the most up-to-date route information.

What kind of scenery and natural features can I expect along the way?
You'll experience diverse landscapes, including winding through Kilauea Woods with towering Albizia and Norfolk Island Pines, and the United States' largest Mahogany Forest. The trail also offers expansive views of the West Makaleha Mountains and Mount Namahana, passes community gardens, guava orchards, and the Kalihiwai Lagoons.
What are the main highlights along the route?

What should I bring for a hike on this route?
