Treman S. P.

Tucked into the glacially carved landscape of the Finger Lakes region, Robert H. Treman State Park delivers one of New York's most dramatic natural swimming experiences. Here, Enfield Creek tumbles through a breathtaking gorge before pooling in a cool, clear basin at the base of a waterfall — and that pool is exactly where you want to be on a sweltering summer afternoon. The sound of rushing water echoes off ancient stone walls, hemlock boughs filter the sunlight, and the air carries that particular chill that only comes from shaded gorge country.

The Setting and Landscape

The gorge at Treman is a geological showpiece. Sheer, layered rock walls rise above the creek corridor, carved over thousands of years into dramatic formations that make every glance upward feel like a reward. Waterfalls cascade in stages along the trail system, but the centerpiece for swimmers is the natural pool below the falls — a wide, inviting basin where the water collects in shades of green and blue. Surrounding forest presses close, and in late summer the canopy creates a cathedral-like hush broken only by the falls and the laughter of other visitors. Come autumn, the same gorge ignites with foliage color, making it a destination for hikers and photographers long after the swimming season ends.

What Swimming Here Is Like

The designated swimming area sits directly below the falls in a deep natural pool fed by Enfield Creek. The water is characteristically cold — bracing even in midsummer — and carries the clarity you'd expect from a creek-fed system in a largely forested watershed. Diving is permitted in the pool below the falls, making this a spot where the adventurous can leap from rocks as well as wade in from the shallower edges. Swimming is officially sanctioned only in this pool, not in the gorge itself, so you'll want to respect those boundaries both for safety and preservation. The moderate hike required to reach the upper gorge trails means the main swimming area stays energetic and social, drawing families and groups who appreciate having a genuine natural setting paired with reasonable amenities.

Plan Your Visit

Robert H. Treman State Park charges an entrance fee, so plan accordingly. On-site facilities include toilets, changing rooms, showers, and picnic tables — a solid setup for a full day out. The park also offers camping, and while most sites are fairly open and close together, sites numbered 20 through 35 offer more tree cover and a woodsier feel if you want to extend your stay into the evening. The swimming season runs roughly from late May to early September, which is also when the park sees its highest visitation. Trail footwear is recommended if you plan to explore beyond the swimming area, as the gorge paths can be uneven and damp. The park sits just outside Ithaca , a vibrant college town with excellent dining, farmers markets, and additional waterfall destinations of its own — making Treman an easy anchor for a longer Finger Lakes adventure.

Named after Robert H. Treman, a philanthropist dedicated to conservation, the park reflects his vision for preserving New York’s natural beauty.

Visitors are encouraged to follow Leave No Trace principles, avoid littering, and respect wildlife to preserve the park’s ecosystems.
