Twin Falls is the first proper waterfall stop on the Road to Hāna, just past Mile Marker 2. The lower falls are a 5-minute walk from the parking area; the upper falls (and the swimming pool below them) are a longer 30-minute hike on a rocky path. A fruit stand at the gate sells fresh-cut coconuts and banana bread.
What to know
- Cost: $10 parking, cash or card at the stand.
- Hours: Daily, daylight only.
- Time needed: 45 minutes for lower falls; 1.5–2 hours if you hike up.
- Footwear: Real shoes, not flip-flops — the upper trail is muddy and rocky.
- Best move: Hit Twin Falls first, before 9 AM. Tour vans don’t usually arrive until 9:30–10.
