Ron posted these pics on GoOutsideBook and boy, do I wanna go hike there now!
They're located in Ricketts Glen State Park in PA where there are 22 waterfalls, 21 are on the 7.2 mile Falls Trail. I don't know when I'll get there, but I know that hitting up that trail would be really fun! There's also a shorter loop trail that would make a great shorter hike for those who just want to catch a glimpse if you leave from the Lake Rose trailhead instead.
If you're in the area, it looks like a great place to check out!!
