The jungle is thick in Kalalau valley, so you'll need to search
with care. Begin by taking the main trail into Kalalau Valley (the
one going up to "Big Pool"). Keep an eye out for the less traveled
paths. After you cross a small stream with water take a side trail
to the left. The main trail goes up the ridge with many stone
walled terraces. You reach a great valley viewpoint if you go up
the ridge.
Avoid the little ones, and look for the great boiling pot, just
up from there is a large rock with a path into the woods leading to
a hole in the wall... You know about boiling pots, right???
The cache is hidden about 4 feet above ground.
Small note on cache maintenance: I, and two
friends, visit from Oahu regularly. Between the three of us we
should be able to check in with the cache every two or three
months.
