Getting there

Manawaiopuna Falls sits about 4.4 miles north of Kalaheo in Kauai County. Navigate to the coordinates 21.98835, -159.52556, which mark the waterfall itself; the trailhead or parking area may be some distance away. Reviewers describe the approach with easy-access language.

Open directions in Google Maps or Apple Maps, or view the map on the Manawaiopuna Falls listing. Navigation apps sometimes route onto seasonal forest roads, so check road status if you are heading into the mountains.

Many of Hawaii's best-known falls are in state parks or national parks, while others sit on private land, in watershed areas or in botanical gardens that charge admission. Several popular sites, including Haena State Park at the start of Kauai's Kalalau Trail, use reservation or entry systems for out-of-state visitors, so checking current requirements is wise. Parking is tight along the Hana Highway, and stopping on narrow shoulders is dangerous and often restricted. The biggest hazard is flash flooding: streams can rise within minutes from rain falling far upslope, stranding hikers at crossings. Rockfall beneath falls is common, freshwater can carry leptospirosis, and trails turn very slick with red mud. Respect closures and no-trespassing signs, which are frequently posted at informal access points.

What to bring

This checklist is tailored to Manawaiopuna Falls based on what visitors report and the conditions typical of Hawaii. For the complete list, see our waterfall hike packing guide.

• Offline map and coordinates. Save 21.98835, -159.52556 and download offline maps; cell service is often weak near waterfalls.
• Shoes with real grip. Rock near falling water stays wet and slick even in dry weather.
• Water and a snack. More than you think you need, even for a short walk.
• A light rain layer. Spray from the falls and quick-moving showers can soak you.
• Rain gear and insect repellent. Hawaiian waterfall trails are often muddy, and stream levels can rise quickly after upstream rain.
• Headlamp. In case your visit runs later than planned; check sunset time in the conditions panel above.

How to prepare

Timing

Hawaii has falls year-round, but flow depends on recent rain far more than on season. The wetter months generally run from about October through April, when winter storms add to trade-wind showers and falls along the Hana Highway, the Hamakua Coast and Kauai's interior run strongest. Summer trades still bring regular windward showers, so many falls keep flowing, though some smaller ones shrink to a trickle during dry spells. Morning visits tend to be clearer, calmer and less crowded, and they are best for rainbows at Rainbow Falls in Hilo. Heavy rain can arrive suddenly in any month, and north-shore winter surf affects coastal trailheads on Kauai and Oahu. With 35 reviews, it sees fewer visitors than the region's headline falls, so you may have it to yourself on a weekday.

Safety

Stay behind railings and off wet rock, never climb on the falls, and keep children within arm's reach near the water. Check the weather panel above for flood or storm alerts before you set out; water levels can rise fast after upstream rain. Our waterfall safety guide covers the most common hazards.

Respect the place

Pack out everything you bring, stay on established paths to limit erosion, and leave rocks and plants where they are. See Leave No Trace at waterfalls.

History of the area

Older maps and records also list it as Mana Waipuna Falls and Hanapepe Falls.

The federal gazetteer describes it this way: On a westward flowing tributary of the Koula River, on the island of Kauai, about 4.5 mi N of Kalaheo and 7 mi NNW of Koloa.

Manawaiopuna Falls was entered in the Geographic Names Information System on February 6, 1981, and it appears on the USGS Koloa 7.5-minute topographic map.

The U.S. Board on Geographic Names made a formal decision on its name on January 1, 1965.

Its neighbors on the map tell the story of the surrounding land: Kālai Stream (stream, 0.8 mi), Paliemo Valley (valley, 1.0 mi), Hulua (summit, 1.0 mi), and Puuauuka (summit, 1.2 mi).

Kauai. Kauai leads the state with 40 named falls. Its central peaks are among the rainiest places on Earth, and the runoff has carved the island into ridges, valleys and amphitheater-headed canyons. On the east side near Wailua, Wailua Falls is a roadside double fall seen from an overlook, and Opaekaa Falls is viewed from a distance across a lush valley. Hoopii Falls near Kapaa is reached by a muddy forest trail. On the north shore, Hanakapiai Falls lies inland along the Na Pali coast, while the Waimea and Kalaheo areas on the drier west side give access to canyon-rim views of falls in Waimea Canyon and the interior.
