Kauai is a landscape photographer's dream: Na Pali Coast, spectacular beaches, tropical sunrises and sunsets, Waimea Canyon,...the list goes on and on. Something that is truly unique is the wave action at Ke'e Beach in the winter when the surf is high. Just off the beach are some cliffs. The high waves come rolling in, hit the vertical cliffs, and then those waves bounce back and go the other way back out to sea. Those bounced waves hit the incoming waves, and the result is spectacular "constructive interference". I've had the pleasure of being at Ke'e Beach on several occasions of high surf. Maybe these waves occur elsewhere in the world, but I've only seen them at Ke'e Beach. You can photograph them from the main beach, or get closer via an unofficial "herd" path.
