Hells Hollow Falls sits inside McConnells Mill State Park, so the walk in comes with the park around it: marked trails, signed junctions and, usually, other things worth a stop on the same day.
The draw here is the moment the sound reaches you before the water does. People plan whole days around falls like Hells Hollow Falls: a walk through the woods, cold spray at the base, and a quiet spot to sit for a while.
Geology and background
What makes Hells Hollow Falls special
Hells Hollow Falls is a McConnells Mill State Park fall in Pennsylvania, and the hollow is the story. The fall drops into a deep, shaded hollow where the creek has cut down through the rock, and the air stays cool even on a warm day. Breakneck Falls is 2.8 miles away, Kildoo Falls 3.5 miles away and Alpha Falls 3.9 miles away, so the fall is one stop in a small park set rather than a lone destination.
No stream gauge is linked to Hells Hollow Falls, so recent rain is your best guide. Expect the most water in spring and after heavy rain. In a dry spell, especially late summer and early fall, the same fall can look half the size.
Navigate by coordinates rather than by name. Map apps often send waterfall searches to the wrong parking lot or the far side of the stream. Download an offline map before you lose signal.
Best time and crowds
No stream gauge is linked to Hells Hollow Falls, so recent rain is your best guide. Expect the most water in spring and after heavy rain.
McConnells Mill is busiest in spring and summer. Arrive early or late: the middle of a summer weekend is peak time, and the park’s parking areas can be full by late morning.
Safety
Stay on marked trails and behind railings. Wet, mossy rock near the brink is the most common cause of serious injury. Never climb the cascade or stand at the top edge, even when the flow looks gentle. In canyons, rain upstream can raise the water in minutes: leave if the water turns muddy or starts to rise.

Practical tips
Pair it with Breakneck Falls, 2.8 miles away, and Kildoo Falls, 3.5 miles away.
Screenshot the directions and these coordinates before you leave town.
Wear shoes you do not mind getting wet: spray reaches further than you expect.

A waterfall is a stream caught in the middle of reshaping its valley. The plunge pool at the base is scoured out by falling water and the stones it carries, and the lip retreats a little with every flood.
Water flow and seasons
No stream gauge is linked to Hells Hollow Falls yet, so recent rain is your best guide. The weather panel on this page adds up the last three days of rain at the fall.
Flow tends to peak in spring with snowmelt and seasonal rain, and again for a day or two after a big storm. By late summer smaller falls can drop to a thin ribbon.
The trail and the viewpoint
We do not have a trail length for Hells Hollow Falls yet. Some falls are a few steps from a parking area, others take a real hike, so check the park or a trail app before you set out.
Swimming is not listed. Treat the plunge pool as off-limits unless signs say otherwise: the water at the base is colder and stronger than it looks.
Facilities and amenities
Facilities depend on McConnells Mill State Park: larger parks usually have a signed trailhead, restrooms and a parking area, while smaller reserves may have none of these.
Plan as if there is no drinking water and no phone signal at the falls themselves. Use the restroom and fill your bottles before you start walking.
Fees, permits, and opening hours
No entry fee is listed. Parks may still charge for parking or day use, and federal lands often accept an annual pass instead.
Most falls are reachable from dawn to dusk. Gates, seasonal road closures and timed-entry permits are the usual surprises, so check the managing agency on the day.
How to get to Hells Hollow Falls
Hells Hollow Falls is in McConnells Mill State Park, Pennsylvania. For the last stretch, navigate by coordinates (40.9301, -80.2319) rather than by name. Map apps often send waterfall searches to the wrong parking lot or the far side of the stream.
The final approach is usually the hardest part: narrow roads, small trailhead lots that fill early, and a walk that can be ten minutes or several hours. Download an offline map before you lose signal.
Our Pennsylvania waterfalls page maps every fall in the state, which helps when you are planning a route.
For the fullest flow, visit Hells Hollow Falls in spring or within a couple of days of heavy rain. For easier footing and warmer air, early summer is the compromise.
Light matters for photos: the base of a fall is often in shade by midday, and an overcast day evens out the bright water against dark rock.
Crowds and timing
Weekday mornings are the quietest. On summer weekends, popular falls can fill their parking by mid-morning, and the viewpoint becomes a queue.
Holiday weekends and the first warm days of spring are the busiest of all. If the lot is full, do not park on the road shoulder: it is the most common reason for tickets and towing at trailheads.
How long to spend there
Without a listed trail length, plan for half a day: enough time to find the trailhead, walk in, spend an hour at the water and walk out without rushing.
If there are other falls nearby, they are often on the same road or trail system. Two or three in a day is very doable.
