If you love waterfall, you have got to visit Silver Falls State Park in Oregon. There are ten wonderful waterfalls in one park! I was also impressed by the trail system there. Not only you can see the falls from the bottom, top, or side, but also, for some of them, you can even go to the back of the waterfall. Walking underneath the fall and seeing the water falling over head was amazing. Highly recommend this State Park, if you happen to be in Oregon.
PS. The only bad part, for me, is it was mostly cloudy and dark on the day I was there. 😦
