Trail Breakdown
Segment 1: Trailhead to Flat Section (0 – 0.5 mi)
Starts at the green gate, wide and flat path—good for warming up.
Little shade; wear a hat, sun-protective clothing, and sunscreen.
Segment 2: Forest to Junction (0.5 – 1.2 mi)
Enters dense forest, cooler and more humid.
At the first signpost, turn right for Waimano Falls Trail.
Path becomes rocky and root-covered—watch your step.
Segment 3: Steep Descent (1.2 – 1.5 mi)
The most challenging part: steep downhill into the valley.
On the return, this becomes an uphill climb—nicknamed the “Cardio Hill.”
Slippery when wet; ropes available but check stability before using.
If water flow is strong, you’ll start hearing the falls here!
Final Section: The Waterfalls (1.5 mi mark)
Two-tiered falls await:
Lower pool: Main area for swimming, cliff jumping, and the rope swing.
Upper pool: Accessible via rocks on the left side. Shallower but offers the best views and photo angles.
Safety tip: Always check depth and surroundings before entering natural waters.
Best Time to Visit
Time of day: 7:00–9:00 AM—cool, quiet, best lighting for photos.
Season/weather: 1–3 days after rainfall for the most impressive water flow. During dry periods, the falls may reduce to just a small pool. Ask returning hikers about conditions.
