Riding for a Fall: Foliage That Is: When to Go and Where to Stop
The Oxford English Dictionary has over 200 meanings for the word “fall.” As a verb, it broadly means dropping from a higher place to a lower.

The Oxford English Dictionary has over 200 meanings for the word “fall.” As a verb, it broadly means dropping from a higher place to a lower.
That definition is superbly illustrated along the GAP in the Allegheny Mountains. Leaves fall from branches to the ground; peak color falls from higher to lower elevations – from ridge tops to valley bottoms.
Best Time to Go
Peak color along the GAP typically runs from the end of September through late October, with mid-October as the sweet spot.
The trail’s high point is 2,392 feet above sea level at the Eastern Continental Divide, and color begins there first, then spreads down to lower elevations and river bottoms – meaning you can chase peak hues by moving along the route.
A few practical notes for timing your visit:
- Mornings are still and give you soft, low-angle light plus river fog, especially around Ohiopyle and Confluence.
- Because leaf color timing shifts year to year with temperature and rainfall, check Pennsylvania DCNR’s weekly fall foliage report (Thursdays beginning late Sept.) for up-to-date information before you head out. This year has had plenty of rain, so the outlook for vibrant color is good.
- If you can only pick one weekend, aim for the third weekend of October – it’s the most reliable window for full color.
- Watch the daily weather and be ready to visit on bright, sunny, blue-sky days after a cold front comes through the region.
Where the Best Views
The richest stretch for foliage is between Big Savage Tunnel and Big Inch Overlook, threading the Youghiogheny and Casselman River gorges. Riding east to west is a popular direction for a fall trip since it’s downhill all the way. Here are the standout stops, listed by mile marker:
Big Savage Tunnel Vista (mile 21.5) – Just beyond the east portal of the 3,294-foot tunnel is a dramatic panoramic view of the Appalachian Mountains of central PA with views into three states.
Salisbury Viaduct (mile 33.7) – Near Meyersdale, this 1,908-foot viaduct gives a full 360-degree view over farmland, the Casselman River, and hillside color.
Pinkerton Low & High Bridges / Pinkerton Tunnel (mile 51.5) – Twin spans over the Casselman River with mirrored reflections, leading into the 849-foot Pinkerton Tunnel, whose far portal frames the color beyond. The 1.5-mile Pinkerton By-Pass is a less-used route and is especially beautiful in autumn.
Ohiopyle Low and High Bridges (mile 71.9) – Steel trusses frame Ohiopyle Falls from the Low bridge, and the High bridge stands 100 feet above the Yough River, laced with early-morning fog. This area is popular, but an early-morning mid-week visit is less crowded.
Big Inch Overlook (mile 79.3) – Marks the location of the historic Big Inch pipeline, listed on the National Register of Historic Places (NRHP), and buried beneath the trail and crossing under the Youghiogheny River. The view of the lower Yough River, wrapped in forests, is worth seeing year-round.
To pick where to begin, use the GAP – Allegheny Highlands Mapsite, which has all of the trailheads along the trail between Cumberland and Connellsville. Other map layers include GAP features and amenities to make your ride more enjoyable.
Don’t fall behind. Plan now and enjoy the season’s splendor.
