Driving across Kauai, Hawaii’s Garden Island, is shorter than on larger islands but still requires careful planning. Without stops, a full traverse takes about 3 hours, but with traffic, scenic viewpoints, and breaks, most drives take 4–6 hours. The main highways, Route 50 (south/west) and Route 56 (north/east), intersect at Lihue. The Na Pali Coast and single-lane bridges limit continuous driving, making early starts and strategic planning essential for a smooth trip.
