Puu Oo Trail

Hawaii > The Big Island > Mauna Kea
Summary
Length7.4 mi
Elev. Gain420 ft
Difficulty3 / 5
Rating7 / 10
TypeView
The trail is located at an altitude of 6000 feet and runs through grassland, emerging forests and native forests lined with lava flows of many ages. According to history, this trail was originally used by Hawaiian cowboys who used to drive cattle to the ships in the harbor at Hilo.

Start the trail at the rim of the parking lot to soon enter a forest of Ohia trees on top of a 400 year old lava flow. Pass through the trees and climb over an edge and again climb over a second edge. You can see the Mauna Kea and the Mauna Loa from here.

Descend the second edge and land on a grassland bordered with Ohia and Koa forest on both sides. After a journey of a quarter mile on the grassland, the trail reaches a small area of Koa trees. From this Kipuka (small island of forest surrounded by lava flows), the trail runs through another forest of Ohia trees and lands on another grassland crossing two more Kipukas.

The next phase of the trail makes you cross a number of Kipuka and lava flows before you enter into the Tall Tree Kipuka. Come out of the Tall Tree Kipuka and head towards two more lava flows. Again, cross three more Kipukas and two more branches of ancient lava flows before reaching the Powerline Road. From the Powerline Road reach the Saddle Road from where turn left and after 0.75 mile you will reach your car.
