Stroll through the gardens and grounds of this magnificent castle with a tragic love story. Admission to Heart Island and free reign of the grounds will run you about $10 ($7 for children). There are shuttles from Alex Bay for another $10. It's worth it!
Swim in the clear waters of the river! The pavilion ("Main Dock") is 10-12" deep, and best suited for strong swimmers. For beginners, the Cove is a shallow alcove with a floating dock - perfect for observing fish!
As the great connector of the Great Lakes and the Atlantic, the St. Lawrence has a lot of commercial and historical influcence. Take a boat tour from Alexandria Bay or Clayton and learn about the river's history of pirates, trappers, religious figures and Victorian-era elites.
