Koko Head Rim Trail is a 3.6 mile moderately trafficked loop trail located near Honolulu, Hawaii that features beautiful wild flowers and is rated as moderate. The trail offers a number of activity options and is accessible year-round.
This trail is sometimes also called the Hanauma Bay Rim Trail. It is an easy to moderate trail located west of Hanauma Bay and is NOT open to public, even though many locals tend to use it for a good run. There are FCC and telecom infrastructure at this location. Koko Head is often mistaken for Koko Crater. This one is on the makai (ocean) side of the state and national parks and is not the tuff cone with the railway line. This lessor known trail starts at the Hanauma Bay bus stop with a road that leads up the hill towards the ocean. Note that this is not a public area, so visit at your own risk. There is lots of history in this area. According to Hawaiian Folk Lore, one of the stories talks about 3 brothers of which the youngest Kaneapua disobeyed his brothers and therefore, the spring water that we was sent to collect dried up. Likewise, there are two depressions called Ihiihilauakea and Nonoula. Both are normally bone dry, but Ihiihilauakea at times will fill in the spring sprouting a four leaf clover that is endemic to Hawaii. This trail has no cover so bring lots of sun screen. It is also normally very windy. The main attractions are the four leaf clover bloom in the spring and a sea cliff rock bridge that is located just past Pai'olu'olu Point.
Great trail! First part is easy and on a paved surface. There are good inclines and even better views of Hanauma Bay and Koko Head.
Shorter hike but has its challenges! No shade so make sure to have sunscreen and a hat. The views are rewarding and there is a good balance of inclines and flat areas. You can park in the same lot as the Koko Head Trailway and if you walk up to the left and follow the paved path it will take you back to the highway. Just cross the street towards Hanauma bay and you'll see the trailhead on the right after you pass the bus stop.
Amazing views! Don't be deterred by the no trespassing signs! The security guard told us to proceed and so glad we did! Views are incredible the whole way! Trail says moderate but the whole way is paved so you can definitely stop along the way if you need to!
