I remember the last time I hiked to a waterfall.  Back in my college days our photo class got together for field trips.  We took photos of each other in the water.  There wasn’t much water in San Diego so the waterfall was really small.  Secret Falls was quite different.  The quantity of water is much greater and the height from which it falls much higher.  To get there we chose Wailua River Guides.   People are really nice at the shack where we checked in and borrowed footwear.  I found a pair of KEENS.  They require closed toe shoes to trek through streams and mud.  A quick van ride…
