At about .6 mile you'll round a bend to an overlook with a stone fence. The large stone "window" over to your right gives the falls its name. Stone stairs to the left go to the base of the falls.
These falls are in two sections; the upper is visible only by scrambling through the window or around the rock face directly below it. Either way, the footing is tricky. If you make it to the other side, you're apt to step in the stream and get the soles of your shoes very slippery. This will make your return scramble even more precarious.
The creek tumbles over a 30-foot cliff to form the lower section of the falls. Keep a safe distance from this drop-off.
The lower section of the falls offers even more scrambling opportunities, including walking behind the waterfall (great for taking pictures). Again, be very sure of your footing and don't let your kids out of your sight.
This area can be very fun and challenging, but any slip can be tragic.
When you're done, retrace your steps back to the parking lot.
