About Wailua Falls

Wailua Falls is one of Kauai’s most photographed waterfalls, plunging from the South Fork of the Wailua River near Lihue into a verdant, fern-lined gorge. Sources vary on its height—local measurements often cite an 80-foot drop, while Wikipedia and other references list the falls at about 173 feet (52.7 m)—but either way the twin tiers and the constant plume of spray make it a dramatic sight. The falls were made even more famous by appearing in the opening credits of the TV series Fantasy Island. The site sits within Wailua River State Park and is managed by SPR (Hawaii State Parks), so it’s easy to access for a quick visit from the roadside lookout. Although Wailua Falls is primarily a drive-up destination, there are informal paths that lead down toward the base. Hikers and photographers often follow these unmaintained routes for closer views, but expect muddy, slippery, and uneven footing—especially after rain. If you want a short outdoor outing rather than a mere pull-off photo stop, plan for a moderately paced excursion and exercise caution near cliff edges and wet rocks.

Height: 80 feet

Trail Description

Trail length: ~2.4 miles (out-and-back); Elevation gain: ~350 ft; Difficulty: Moderate; Trail type: out-and-back; Height at falls: reported 80–173 ft. There is no official, maintained trail to the base—the route consists of informal, unpaved paths and primitive tread that can be muddy and slippery. Terrain is uneven with some steep sections and exposed footing; expect natural surfaces (dirt, roots, mud) and limited signage. The roadside lookout provides safe viewing without descending; only attempt the path to the bottom if you are comfortable on unmaintained trails and in wet conditions.

What to Expect

Visitors can expect a breathtaking view of a double-tiered waterfall surrounded by lush tropical vegetation. The falls are especially impressive after heavy rainfall, though this may also make the area slippery and hazardous.

Accessibility

The lookout area is accessible by car and does not require hiking. However, the viewing platform may not be fully wheelchair accessible due to uneven surfaces.

Seasonal Closures

Wailua Falls is open year-round and does not have seasonal closures.

Safety Information

Do not climb over barriers or attempt to hike down to the base of the falls, as the terrain is steep, slippery, and dangerous. Flash flooding can occur after heavy rain, so exercise caution during wet weather.
