The Ka'au crater lies close to the crest of the Koʻolau Range.
A marsh sits in the crater, with water feeding the streams and waterfalls of the valleys below. This 7.3-mile loop trail (if you do the entire loop) is considered strenuous. The hike starts at the end of Waiomao Road, with a rather inconspicuous trailhead located behind a row of mailboxes. Do not enter private properties or driveways that flank the sides of the trail. Immediately, hikers must scramble down some boulders and are surrounded with lush tropical forest. The trail makes its way along the side of the riverbed, including multiple crossings, and begins ascending gradually. You will come across a point in the trail where you can go clock-wise or counter-clockwise around the loop. To visit the waterfalls go right. To go straight up to this geocache, go to the left.
Be sure to bring plenty of water for this demanding hike. On clear days, the exposed ridge section can be brutally hot and sunny. On wet days or after the rain, the trail will be slick and muddy.
Geocache at your own risk.
