Koko Crater Arch Trail
A hiking area with a challenging trail and panoramic views, ideal for hikers looking for a scenic workout.
Koko Crater Arch Trail is a short but steep hiking route on O‘ahu’s south shore that leads to a natural rock arch with wide views over the ocean and the surrounding volcanic landscape. The trail is known for being rugged and exposed, with uneven footing and little shade, so it feels more like a serious outdoor climb than a casual stroll. It’s a rewarding stop for hikers who want a dramatic coastal viewpoint and a memorable geologic feature in a compact outing.
History
The trail is part of the Koko Crater area, a volcanic tuff cone formed by ancient volcanic activity on O‘ahu. The arch itself is a natural erosion feature shaped over time by wind, waves, and weathering along the island’s coastline.
Expert notes
- Wear sturdy shoes with good traction; the path can be loose and uneven.
- Expect little to no shade, so sun protection is important.
- Check local conditions before going, especially after rain, since the trail can become slippery.
