Oswegatchie River.

The Oswegatchie River cuts through the western edge of the Adirondack Park — a slow, winding waterway that defines the Five Ponds Wilderness and draws paddlers looking for multi-day flatwater routes far from the High Peaks corridor. The upper sections offer remote camping and access to a sprawling backcountry pond system; downstream stretches pass through mixed forest and old-growth stands before eventually leaving the park boundary near Cranberry Lake. It's a working river — logging history, carry trails, and a reputation for solitude rather than scenery. Launch access varies by section; most paddlers start from the Inlet or Griffin Rapids depending on how deep into the wilderness they're willing to commit.
