A relatively short hike, the Koko Crater Trail is only about 1.5 miles (from parking lot to the summit), but increases in elevation by 1,200 feet! This hike is challenging due to the sharp incline, but the views at the top are well worth the effort; you’ll get a breathtaking 360 degree view of east O’ahu. Koko Crater is a cinder conem, not to be confused with Koko Head, which is a much shorter cinder cone volcano that forms Hanauma Bay
On the inside of the crater you can find Koko Crater Botanical Garden
s which has a great variety of dry land plants.
The railroad ties that make up the stairs for the trail were once part of an incline tram system during World War II, which was used to haul military personnel and supplies to the top of Koko Crater. This area was a part of the Koko Crater Air Force Station.
