I don't know about you, but I love Hawaii.
My favorite island is Kauai, which I visited in December 2017.
The photo below shows Red Dirt Waterfall. This amazing spot on the road to Waimea Canyon is very easy to miss, as there is no sign anywhere.
The red soil gives the spot a very Mars-like appearance.
