This trail ascends out of a residential neighborhood in the historic ranch town of Kamuela, and ends atop the majestic Waipio Valley. Best on a clear day, and even if clear, best after a period of dry weather!

The initial ascent is very steep, but green pasture land provides the grip needed. This crosses through Parker Ranch, so please proceed at your own risk. The 4x4 trail from Opelo Rd. can be followed to the reservoir above, where it turns into 2-track broken pavement and gravel road.

Above the reservoir this trail enters state lands: Kohala Forest Reserve. The 4x4 road follows important water infrastructure all the way to the end, and the origin of Waipio Valley. This section of the trail, although hard-packed, can be technical and fun due to the erosion from torrential rains.

Enjoy the breathtaking views! On a clear day you might be able to see all the way down the valley to the coast, and then Mauna Kea over your shoulder. Be careful not to get to close to the cliffs.

For the adventurous: follow the road to the aqueduct, and take a left. If it's dry enough, there is a foot-path that follows the ditch over towards the next valley.

 FYI: This is not a sanctioned trail and it is considered trespassing not only through Parker Ranch land but also when entering the State Water Shed area. Both are monitored and you could be arrested and fined.
