Hiking this trail was on my bucket list for our family trip to Oahu because GC23 is located on the trail. This geocache was placed in July 2000 and is one of the oldest ones I've ever found. There is also an easy "History of Geocaching" near the end of the trail. We were short on time and my family opted to wait for me in the parking lot so I didn't hike the whole trail. I started at the "end" of the trail (down the steps from the large parking area) instead of starting at the "start" (by the bathrooms). The GPSr said it was only .2 miles away, but that's as the crow flies. It took me 38 minutes to hike out to the geocache and 22 minutes to hike back - I didn't do the entire loop trail. It was dry when I went. The cache itself is an ammo can secured to a tree. It's the history that makes it special.
