The Ka’au Crater Loop hiking trail is around 5 miles (7.5 kilometers) and takes around five hours to complete. Many travelers say that it is quite a challenging and difficult hike, especially after rain, when the ridges are muddy. That said, experienced hikers should be able to complete it.

While the Ka’au Crater trail is marked with pink ribbons tied to trees, they can be easy to miss. It’s a good idea to bring a map or download a GPS map onto your phone before setting out on the trail (cell service can not always be relied upon).

The trail can indeed be risky. Because the trail runs through a rainforest, expect several slippery sections. Many people have needed rescue, and some have died. It’s best to hike in the company of an experienced hiker who knows the trail well. Prioritize proper footwear to avoid slipping.
