As we follow Ekaha Valley higher and higher we once more come to a well worn trail and see Yellow markers. Yup, it's the Wai`anae Ramble again. We turn left on to it for a few minutes. We'll cross one small stream and then come to another. Both feed into Ekaha. Before crossing the second stream we cut hard right and begin to climb steeply on a narrow trail. After about 10 minutes on the ridge trail we come to a small trail on the left. This takes us down to the stream again and tunnel #14. This is the 400' long tunnel that we can enter. It dead ends and one must come back out. Here the trail cuts thru thick brush.
When we come to the stream again we are about 30' from the tunnel. Since I have a Geocache http://www.geocaching.com/ in the tunnel I have no picture of the entrance nor will I say any more about the entrance. After this introduction there has to be a little of a challenge.
