It's illegal to run the Falls above 1.8 feet.
While the put-in for the Lower Yough is located immediately downstream of the Falls, boaters are not allowed to take out here and must continue down the Lower Youghiogheny. If your primary goal is running the Falls, you can take out at the Loop Take-Out, 1.4 miles downstream at High Bridge on river right, and make the short 0.2-mile walk back to the Ferncliff Trailhead where you started. Alternatively, you can continue with your group on the full Lower Yough run and take out further downstream at Bruner Run Access.
