Stony Brook State Park
Stony Brook State Park is a dramatic Finger Lakes gorge park in Steuben County, New York, where a rushing stream has carved a deep sandstone canyon decorated with three impressive waterfalls — the 40-foot Lower Falls, 20-foot Middle Falls, and the towering 45-foot Upper Falls. With a natural stream-fed swimming pool, gorge-bottom hiking, and a peaceful campground above the rim, Stony Brook is one of the Finger Lakes region’s most beautiful and accessible natural attractions.

The Gorge & Waterfalls
Stony Brook’s gorge is the star — a slot canyon of towering sandstone and shale cliffs carved over millennia. The creek descends through the gorge in a series of cascades and pools, passing three named waterfalls:
- Lower Falls (40 feet) — the first major cascade, visible from the Gorge Trail
- Middle Falls (20 feet) — a wider, gentler curtain of water
- Upper Falls (45 feet) — the tallest and most dramatic, tucked deep in the gorge
Note: Swimming directly beneath the falls in the creek bed is prohibited to protect the environment.
Trails
| Trail | Highlights | Difficulty |
| Gorge Trail (~1 mi) | All 3 waterfalls, canyon walking, rock formations | Moderate (uneven, wet) |
| West Rim Trail | Cliff-top overlooks, forest walking | Moderate |
| East Rim Trail | Overlooks of waterfalls and gorge from above | Moderate |
Trails are not accessible for strollers or wheelchairs due to steep, rocky terrain.
