One of the great features of Silver Falls State Park in Oregon is that on the Trail of 10 Falls you get to walk under and behind a number of the falls on the hike. This is the North Falls and the shot is taken from a cavern under the falls. Quite cool and dark there and I bet it is a welcome relief on hot summer days. I was there a few weeks ago on a cool fall day, perfect for hiking. The hike is supposed to be 7 miles but I was at about 10 miles on my watch and only got to see 4 of the falls. You get a lot of steps going up and down to each of the falls. The shot bellow is a 4 or 5 shot composite to show more of the walkway behind the falls. Interesting view of the falls from that location.
