Thousand Islands

Scenic waterway dotted with charming castle islands

The Thousand Islands aren't just a salad dressing joke. This scenic waterway straddling the US-Canada border serves up actual castles, charming riverside towns, and some of the most relaxed island hopping you'll find anywhere. Sure, there are only 1,864 islands (yes, someone counted), but who's keeping track when you're cruising past Gilded Age mansions and lighthouse-topped islets? The St. Lawrence River carved this playground for the wealthy back in the day, and now it's yours to explore. Just don't expect nightlife beyond a good fish fry and sunset cocktails.

The Thousand Islands stretch 50 miles along the St. Lawrence River between Kingston, Ontario and Cape Vincent, New York. Here's what counts as an island: it has to stay above water year-round and support at least two living trees. Boldt Castle on Heart Island gets all the Instagram love, but the real magic happens when you realize this entire region was basically the Hamptons of the early 1900s. Railroad and shipping magnates built summer "cottages" that put today's McMansions to shame. The American side centers around Alexandria Bay, while the Canadian side claims Gananoque as its gateway. Most islands are privately owned, but plenty of state and provincial parks keep the good stuff accessible. The water stays surprisingly warm through summer – thank the Great Lakes for that thermal boost.
