At the top of this trail is a pink pillbox that provides scenic views in real life, and some instagram worthy content. The pillbox provides some of the best views on this side of the island and being that it is west facing, is ideal at sunset.

Puʻu O Hulu Trail is known by many people under its unofficial name 'Pink Pillbox Hike'. The last section of the trail, leading up the mountain of PuʻUʻOhulu Kai, includes multiple pillboxes (old military bunkers). One of them is painted pink to raise awareness for breast cancer and became the unofficial namesake of the trail.
