Ohiopyle State Park: Kentuck Campground Professional Review and Guide
"Even on a crowded summer weekend, you’ll find some peace
and quiet at any of the walk-in tent-camping sites. The river in the park is a mecca for whitewater enthusiasts, especially the Class III and IV rapids of the Lower Yough (pronounced “Yock”), which follows the river from the launch area at Ohiopyle to the park boundary.
On a summer weekend, the river will be a nearly continuous
line of rafts, canoes, kayaks, and duckies from the put-in to the take-out. On weekends before Memorial Day and after Labor Day, and on most weekdays, it is considerably less crowded."
