Kayaking Oahu's Living Lagoon: He'eia State Park and the Kaneohe Sandbar
A calm-water paddle with big-mountain views, cultural depth, and the island’s most famous sandbar.
Morning light rolls off the Ko'olau Range like a slow breath, green cliffs exhaling mist into Kāne'ohe Bay. At He'eia State Park, the launch is quiet—just the scrape of a kayak on coral-sand and the friendly shove of the tide urging you forward. The bay greets you with soft lapping and a shallow palette of blue-on-blue, a lagoon so clear the patch reefs seem to float. Ahead, the famous sandbar sits just under the surface, waiting for the tide to lower and reveal its pale spine. Out here, the water has a personality: it nudges, it whispers, and sometimes it dares.
Trail Wisdom
Time the Tide
Aim for mid-to-low tide to see more of Ahu o Laka (the sandbar) and enjoy shallower, clearer water. Always check tide tables before you launch.
Beat the Trades
Start early to avoid stronger afternoon tradewinds. If winds pick up, angle your return close to shore where it’s more sheltered.
Protect the Reef
Use reef-safe sunscreen and never stand on coral. Enter and exit snorkel spots from sandy patches only.
Navigation Made Simple
Use Coconut Island and the Ko'olau ridgeline as visual reference points. Mark your launch on your phone GPS for an easy return.

Conservation Note
Use only reef-safe sunscreen and avoid trampling coral or seagrass. This bay supports active restoration and research—treat it like the living laboratory it is.
He'eia’s 800-year-old fishpond (loko i'a) is one of Oahu’s largest and a testament to Indigenous Hawaiian aquaculture expertise and stewardship.
