In 1936, the year the park opened, Larry Woodin of Wellsboro and other Tioga County business owners began a tourism campaign to promote the Pine Creek Gorge as "The Grand Canyon of Pennsylvania". Greyhound Bus Lines featured a view of the canyon from a Leonard Harrison lookout on the back cover of its Atlantic Coast timetable. The bus line's Chicago to New York City tour had an overnight stay in Wellsboro and a morning visit to the canyon for $3. More than 300,000 tourists visited the canyon by the autumn of 1936, and 15,000 visited Leonard Harrison over Memorial Day weekend in 1937. That year more visitors came to the Pine Creek Gorge than to Yellowstone National Park. In response to the heavy use of the local roads, the CCC widened the highways in the area, and guides from the CCC gave tours of the canyon.
