Au Sable River Swimming Holes

Tucked into the wild heart of New York's Adirondack Mountains, the Au Sable River Swimming Holes offer something that polished, developed beaches rarely can: the feeling that you've stumbled onto a secret. The Ausable River carves its way through northern New York in a series of bends, pools, and riffles, and along the stretch near Au Sable Forks, Jay, and Upper Jay, locals have long known where to slip into the current on a hot summer afternoon. These are unofficial spots — no roped-off lanes, no concession stands, just cold, clear Adirondack water and the sound of the river moving over stone.

The Setting

The landscape here is quintessential Adirondacks: forested ridges drop toward the riverbanks, and the air carries the clean scent of pine and moving water. Boulders worn smooth by centuries of current line the shores, offering natural perches for sunbathing between swims. The river corridor is rich with wildlife — watch for great blue herons picking their way along the shallows, and listen for the occasional kingfisher rattling overhead. One of the area's most striking features is the presence of a historic dam near certain swimming spots, where the blend of stone infrastructure and living river creates an atmosphere that feels both timeless and deeply rooted in the region's past. Come early fall, the surrounding forest ignites in amber and crimson, making the riverside an extraordinary place to wade in and look up.

What Swimming Is Like

The Ausable runs clear and cold, fed by Adirondack snowmelt and mountain tributaries that keep the water refreshing even on the warmest July days. You'll find a mix of shallow riffles ideal for wading and deeper pools where stronger swimmers can fully submerge. The current varies by season and location — summer months bring calmer, more manageable flows, while spring and early fall can push the river higher and faster. The riverbed is typically rocky, so water shoes are a smart addition to your pack. Because these are natural, unsanctioned sites, there are no lifeguards present, and visitors should use careful judgment about water conditions and personal swimming ability before entering.
