Ho’omaluhia Botanical Garden
45-680 Luluku Rd., Kāne'ohe
It’s usually around day three or four that you’ll want to get out of the sun—or at least take a break from the beach. That’s where the Ho’omaluhia Botanical Garden comes in. It sits right up against the Koolau Mountain Range, which is as beautiful as it sounds—lush and natural and packed with every shade of green imaginable and unimaginable. There’s also a loop for an easyish walk around the reservoir that was built by the US Army as flood control.
