Twin Falls

Twin Falls sits at mile marker two of the Hana Highway, which makes it the most photographed and least explored waterfall on the entire drive — a function of timing, not merit. Most cars are still moving with the momentum of a long trip ahead, eager to log the miles before the road narrows. We had promised ourselves the opposite approach this time: fewer stops, more time at each one. Twin Falls was where that decision started paying off.

Past the Fruit Stand

The trailhead begins, unusually, through a working fruit stand on private land, where a family sells smoothies and fresh coconuts from a shaded stall and charges a small parking fee that goes toward trail upkeep. We bought two lilikoi smoothies before setting out, which is either the best or worst decision to make before a muddy hike, and carried them awkwardly across the first stream crossing.

The trail itself is short, maybe twenty minutes to the first pool, but genuinely muddy in a way that soaks through anything short of proper hiking sandals. We passed an old sugarcane flume still running with diverted stream water, a relic of the plantation era that somehow still functions a century later. The first waterfall we reached was modest, a curtain maybe fifteen feet high dropping into a green pool cold enough to make Lia gasp audibly on entry.

Finding the Second Pool

The crowds thin considerably past the first pool, where a second, less obvious trail continues upstream to a taller falls that most day-trippers never see. We had it to ourselves for nearly twenty minutes, floating on our backs and watching the canopy move overhead, before a French family arrived and the spell broke gently rather than all at once. I ate a guava that had fallen onto the trail — the smoothie guy told us they were safe to eat, and he was right, and it tasted better than anything from the stand.

When to go: Arrive at opening, around 8am, before the tour vans start their circuit. Skip after heavy rain — the stream crossings become genuinely dangerous and the water turns the color of coffee.
