Sol Duc Valley, Olympic National Park. Washington

Sol Duc Valley, also known as Soleduck, has been carved by the 126 kilometre long Sol Duck River over thousands of years of erosion. Situated in the northwest region of the Olympic National Park, this valley offers some truly magical and breathtaking sights, from roaring waterfalls, to small rapids, to relaxing hot springs. The valley offers both longer and shorter hiking trails to cater for all levels of fitness, as well as some clean and peaceful campsites. Another spectacular feature here is presence of coho salmon which can be seen swimming upstream, and the river is actually famous for being home to all five major salmon species.
