About Kopiliula Falls
Kopiliula Falls is a picturesque waterfall on Maui tucked into the lush rainforest of the Road to Hana corridor. Framed by dense tropical vegetation, the falls provide a peaceful, secluded stop for photographers and hikers exploring East Maui’s verdant gulches. The setting feels remote despite being reachable from the island’s well‑traveled coastal route. The waterfall and access route lie within the Ko'olau Forest Reserve, a State Conservation Area (SCA) owned and managed by the Hawaii State Department of Land and Natural Resources (SDNR). Visiting Kopiliula is best planned as a short, moderately paced hike; the approach rewards you with classic Hana‑area scenery but requires care on wet, slippery ground and at stream crossings.
The Setting
Kopiliula Falls sits at 1,362 feet within Ko'olau Forest Reserve, fed by the West Wailuaiki Stream, in the foothills of Hawaii.

How we calculate this
This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.
