Excerpt from the Na Ala Hele website:
Wiliwilinui Ridge Trail
Trail Length: 3 mi.
Terrain: Open, wet ridgeline
Activity: Hiking, Bicycle
Elevation: 1600 ft
Wiliwilinui Trail begins on a dirt access road through formosa koa and guava forest. As the road climbs up the ridge, it becomes native koa-uluhe forest. The trailhead is about 1.5 miles up the access road. The trail climbs straight up the ridge to a HECO tower. Continue past the tower to the Koolau summit. This trail offers opportunities for viewing a variety of native plants and, from the summit, the leeward coast and Waimanalo. Note: The Wiliwilinui Community Association has been more than cooperative in letting hikers and hunters access State land through their property. Please abide by all rules and regulations of the association.
Directions: From Kalanianiole Highway heading east, turn left on Laukahi Street. Continue mauka (toward the mountain) on Laukahi until you come to a security guard station. Check in with the security guard and then proceed up Laukahi until it ends. Turn left on Oko'a, following the trail signs. Park in the parking area before the cable gate and proceed on foot along the access road to the trailhead.
Trail Information: Stay on the trail. Pack out at least what you pack in. No open fires.
Dog Owners: Hunting may be in progress on or near this hiking trail. Hunting dogs may be off-leash while engaged in the hunt. Hikers must keep their dogs leashed at all times and remove dog waste while on this trail.
Mountain Bikers: Always yield to hikers. Do not slide around corners or slide down the trail. Careless mountain biking damages the trail and causes erosion. If accidents are reported or damage to the trail is extreme, the trail may be closed to mountain bikers.
You DO NOT need to hike the Wiliwilinui Ridge Trail to find this cache, but if you choose to you will (if conditions are right) undoubtedly find an extraordinary view at the end (not to mention at least 5 caches along the way 
).
Once again, stop at the security station (daylight hours only). Tell the guard you are going to the hiking trail and he will give you a parking card. He may ask for ID.
Here are the five caches heading in:
- GC24RMT - Lean On Me
- GC26V67 - Stop and Smell the Koko!
- GC43FV7 - TLP Series - This Little Piggy (Home Base)(there are more piggies if you follow this side trail down)
- GC4B92Z - Lost Peacock!
- GC1B3RT - Cammo Where?
- GCJ3N6 - Wiliwilinui Ridge Cache
