Kaena Point Pillbox Bunker & Cave Trail is a hiking path located near the Ka'ena Point Bird Sanctuary on the northwest tip of O'ahu. To get to this trail you have to first hike in from the Ka'ena Point Trail - North Shore or the Ka'ena Point Trail - West Shore.

Both trails are around the same length and relatively easy and flat but also exposed to the sun and very hot so going early is your best bet.

The hike up to the Kaena Point Pillbox Bunker and Cave is quite short but it's very vertical so expect a fast climb up of around 400 feet in elevation.

Because of the steep climb up, relative danger of old and unmaintained bunkers and caves, and the fact that this is likely not a sanctioned hike and we really can't recommend it.

We list it so you can at least see what it is and what's up there. If you do this hike anyhow, make sure you are well prepared and read Hiking Safety & Essentials before you head out. The views from the ground in there area are amazing and as you go up the mountain they do get even better as you'd expect.

The trail starts at Kaena Point on the outside of the bird sanctuary (not in the fenced in area). This is a remote part of Oahu with scenic views and protected areas with coastal sand dune habitats. This area is a fragile habitat to native plants and seabirds. During the winter months, whales can be seen from the shoreline. But be aware of the dangerous shorebreak in this area - especially during big swells.
