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.
