Length: 7.3 mi • Est. 4 h 26 m
This site is open to the public although it is on privately owned land. The route can be confusing so you may want to download the offline map before you go. This hike is challenging and can be slippery and dangerous. If you don't know how to navigate in the outdoors you should consider another trail that is well-marked OR hike the trail in a counter-clockwise route as far as the waterfall and return the way you came. This is an amazing hike with three waterfalls and gorgeous views of Honolulu, Kaneohe, Kailua, Diamond Head, and Ka'au Crater. This hike is not too challenging until the 3rd waterfall which you climb up to get to the ridge portion of the hike. This is where it got extremely muddy and a bit dangerous. The view from the top of the ridge is incredible! Pack more food and water than you think you'd need, it's very steep and tiring. The trailhead is cleverly hidden behind the mailboxes on left of the road at the end of Waiomao Road which is a right turn off of 10th Street. You will see the hand lettered sign on the tree behind the mailboxes and the trail starts DOWN from there.Show more

#4 - Ko'olau Summit Trail (Pali Puka)
Round Top Forest Reserve
hardYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarGray Star(328)
Length: 0.7 mi • Est. 37 m
Note: This trail has lots of steep areas and cliff faces, so please be careful. The Puka is below the narrow bridge. Its a great short hike, but do not let the length fool you- it is challenging! Though the route is short, the conditions can be windy, extreme, and muddy. The trail that follows a cliff (pali) face up to two notches that supposedly were utilized by King Kamehameha to hold cannons, and to serve as a lookout post. Wear shoes that are sturdy and grip well and look out for falling rocks and loose dirt. remember to test and shake that rock or branch before using it to pull yourself through. Many rocks are cracking and branches are loosening after long use. Not a good hike for kids or pets! This is a risky hike with rock scrambling and people have fallen and been seriously injured in the past. Use good judgement.Show more

Twin peaked Pu'u Konahuanui is the tallest mountain in the Ko'olau range and offers views of the Nu'uanu Valley/Windward Side. A very long strenuous hike that requires starting on different hiking trails to connect to the summit, this is only recommended for experienced hikers. Often a very muddy hike.Show more
