The Thousand Islands Region is a very beautiful and scenic place. It used to be the playground of the rich, and now it is home to Boldt Castle and Singer Castle. Both are reachable by boat and boat tours are daily.
Alexandria Bay is noted for the night life as well as its 4th of July fireworks over Boldt Castle, but beware—traffic is horrible to navigate afterward.

Another famous thing is Bill Johnston’s Pirate Days. People win competitions for the best-dressed pirate.
This takes place in August.

Most of the local places close down after Labor Day weekend and re-open at Memorial Day weekend.
