What to expect on Petroglyph Boardwalk Trail – ʻAiʻōpio Beach loop from Kaloko-Honokōhau National Historical Park

The route takes you on a journey through a rugged coastal environment, where ancient lava flows meet the Pacific Ocean. You'll walk along a boardwalk that passes over incredible rock art, showcasing ancient petroglyphs (Kiʻi Pōhaku) that tell stories of Hawaiian life and early European contact. Further along, the trail leads to the picturesque ʻAiʻōpio Fishtrap and Beach, a favored spot for green sea turtles (honu) to rest, especially visible at low tide. While the boardwalk is flat, be prepared for unpaved paths, soft sand, and loose, jagged lava in other sections; sturdy closed-toe shoes are highly recommended for this varied terrain.

Planning your visit

This trail is accessible for all fitness levels, offering a unique opportunity to connect with thousands of years of Hawaiian history. To make the most of your visit, consider going in the morning to avoid the midday heat and to potentially catch green sea turtles basking at ʻAiʻōpio Beach. Remember to wear sturdy closed-toe shoes due to the rough lava and sandy sections. The park provides a rich educational experience, so take your time to explore the archaeological resources like heiau and fishponds along the way.
