Here's a web page with info about the trail. Point of Interest #15 describes the bunker as:
"continuing on, you will come across a poured concrete bunker which is on the left side of the trail. This is one of two fortifications installed during World War II. The other bunker is on the opposite shore of Kea‘au Bay."
