This is Silver Falls, from the Golden and Silver Falls State Natural Area located NE of Coos Bay. I prefer Silver Falls in the “park” as the dome at the top of the waterfall makes for a very unique water pattern. Not a typical horsetail, curtain, plunge or other waterfall, it is something different.
From Coos Bay, take Hwy-241 until the end of the pavement, and keep going until the dirty gravel road ends. The waterfall is a very short walk up a slight hill (to the left). The path to the right leads you to Golden Falls.
