43. Opaekaa Falls, Kauai
Visually, this is a spectacular waterfall and is one of the island’s few waterfalls that can be seen from the road. It flows year round and therefore is not seasonal. Most of the time it falls in a double cascade but the two sides may become one after a heavy rain. There is a highway overlook which provides a panoramic view of the 40-foot (12 m) wide falls and the valley below. The best time of day to see the falls is in full sunlight when the water sparkles the most. If the day is cloudy the view is less spectacular.
