🏆 Cayuga Launch — Boat launch on Cayuga Lake — the longest Finger Lake at 38.2 miles and one of the deepest lakes in North America at 435 feet
Deans Cove Boat Launch provides access to Cayuga Lake — the longest of the 11 Finger Lakes at 38.2 miles and one of the deepest lakes in the eastern United States at 435 feet. Cayuga Lake’s bottom actually sits 53 feet BELOW sea level — making it one of the lowest points in North America east of the Mississippi! Cornell University and Ithaca College sit at the lake’s southern end, giving the region its famous slogan: “Ithaca is Gorges” (the area has over 150 waterfalls within 10 miles!). The lake is named for the Cayuga Nation of the Haudenosaunee (Iroquois) Confederacy.

About Deans Cove
Deans Cove Boat Launch on Seneca Lake in Seneca County provides access to the deepest of the Finger Lakes — 618 feet deep, making it one of the deepest lakes in the entire United States. Seneca Lake is so deep it never freezes completely and maintains a near-constant temperature year-round. The lake’s thermal mass moderates the surrounding climate, creating the microclimate that supports New York’s premier wine region.
Things to Do
Boating on America’s deepest Finger Lake, fishing for lake trout and rainbow trout (the deep, cold water is excellent trout habitat), kayaking, swimming, and visiting the 30+ wineries on the Seneca Lake Wine Trail.
