Paepae o Heʻeia
An 800-year-old fishpond being restored wall by wall.
The nonprofit that stewards Heʻeia Fishpond rebuilds its kuapa rock wall the old way and teaches while they work. Walking tours and group visits get arranged through their office, and volunteer workdays are the real way in... you'll haul rock. Call or email ahead, this isn't a drop-in stop.
