Far on the east side of Oahu lies the prominent yet challenging Kuli‘ou‘ou Ridge Hiking Trail with beautiful views of Waimanalo and Hawaii Kai.
It may not be as easy as Manoa Falls or Makapu]u Lighthouse but is very similar to Wiliwilinui Ridge. If you plan to hike here, be prepared to set aside a good chunk of time (3-4 hours) to finish the hike. The trail starts in the very back of the Kuli‘ou‘ou Valley and ends at the top of the Ko‘olau Mountain Range with an elevation gain of around 1900 feet. It is an out and back trail, which means you will be coming down the trail the same way you went up, with a distance of around five miles. The rocky terrain and steep stairs are maintained by the Nā Ala Hele program and the Sierra Club, organizations that strive to preserve and protect hiking trails on Oahu. In all, Kuli‘ou‘ou Ridge is rated as moderately difficult but any adventurous hiker should take on this magnificent trail.
