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.
