About Kāhili Falls
Kāhili Falls, often called The Twin Falls, is a picturesque cascade tucked into the verdant interior of Kauaʻi. The falls drop in twin streams into a tranquil pool framed by lush rainforest—an evocative example of the island’s dramatic scenery. Kauaʻi itself is the fourth-largest of the main Hawaiian Islands (562.3 square miles) and lies about 73 miles (117 km) northwest of Oʻahu; the island’s 2020 population was 73,298, giving a sense of how remote and green many of its interior valleys remain. The waterfall sits on private property, so access is limited and requires permission from the landowners or travel with an authorized guided tour. Because Kāhili Falls is not on public lands or managed by a state or federal land unit, trail conditions, parking, and visitor rules are set by the property owners—plan ahead, respect private-access requirements, and follow any directions provided by guides or owners.

Trail Description
The typical route to Kāhili Falls is an out-and-back hike totaling about 2.4 miles with roughly 350 feet of elevation gain and is generally rated moderate. Official surface, grade, and technical trail-class data are not published as the path crosses private property rather than an established USFS or state-managed trail; trail conditions can be uneven and vary with recent weather. Access is restricted: visitors should obtain permission from the landowners or join a permitted guided tour before attempting the hike. Because the route is not a maintained public trail, expect limited signage and variable footing, and confirm current conditions and access rules with your tour operator or the property owner ahead of time.
What to Expect
Visitors can expect to see two stunning waterfalls surrounded by lush tropical vegetation. The area is serene and offers a glimpse of Kauai's natural beauty. However, access is restricted, and visitors must respect private property rules.
