💦 Waterfall Plunge Pool · Kauai / East Side
A famous, easily photographed twin waterfall (featured in the opening credits of the original 'Fantasy Island' TV show) — regional guides explicitly discourage the unofficial trail down to the pool given how steep and hazardous it is, treating this as a viewing destination rather than a swim spot.
Address / Access Point:
Wailua Falls, Maalo Rd, Lihue, HI 96766
Access Notes:
Easy roadside overlook parking; an unofficial, steep, and hazardous unmarked trail descends to the pool below and is explicitly discouraged by regional safety sources given the steep, slippery terrain and lack of official maintenance
