Information on:

Allan H. Treman State Marine Park

805 Taughannock Blvd. (Rt 89)

Allan H. Treman is one of the largest inland marinas in New York State.  It boasts 370 seasonal, 30 transient and 30 dry boat slips.  For folks trailering boats, the park has an 8-lane boat launch ramp.  The marina is an excellent port-of-call off the Barge Canal system at the south end of Cayuga Lake and within easy walking distance to the city of Ithaca along the Cayuga Waterfront Trail.  For bird watching fans, the Hog Hole wetland and the Cayuga Lake shoreline make for great opportunities to view waterfowl and wetland species. 

This is a marina only park.  We're often confused with Robert H. Treman State Park, which is located 4 miles to the south, not on Cayuga Lake.


Household pets only; caged or on a leash not more than 6 feet. Certificate proof of rabies inoculation.

No hassles. Easy to launch with 8 lanes. Easy access to Cayuga Lake. Lots of parking.

Nice walk around the park. Not much happening during a cool day in April.

My boat needed a jump start due to a dead battery, the park staff was quick to help and would not let me tip them. Thank you to the two women who helped.

I just love open spaces, especially when they're by water. And this park has it. You can take your dog to the enclosed play space, or stroll out towards Cayuga Lake. I explored a little patch of woods near the lake, before checking out the marina. The way the empty slips rested on the ice really caught my attention. I can't wait to see this place in the Spring!!

Nice playing fields. Walking trail us a little confusing, but overall very nice.
