Main Attractions in the Thousand Islands

1. Boldt Castle on Heart Island

This breathtaking castle is full of history and heartbreak. Construction of the castle began in 1900 at the behest of millionaire George C. Boldt for his beloved wife, Louise.

Progress on the castle ceased when Louise passed away unexpectedly in 1904, and George fell into depression.

For 70 years, the six-story castle with 120 rooms remained untouched until the Thousand Islands Bridge Authority purchased it in 1977 with the mission of completing construction and preserving this masterpiece for future generations to enjoy.

Because Boldt Castle is on Heart Island and there are no bridges, you will need to arrive by watercraft. You can drive your watercraft to the island or rent a boat.

Many boat tour companies also offer rides to the castle. Uncle Sam's Boat Tours runs a ferry from the mainland to Heart Island once every 30 minutes. Once you arrive, you can choose to tour the castle, the yacht house, or both.

2. Singer Castle on Dark Island

The regal and luxurious Singer Castle is filled with surprises. This castle was built in 1905 by the Bourne family, who worked with the architect Ernest Flagg. Frederick Bourne was the fifth president of the Singer Sewing Machine Company, which is where the castle received its name.

Singer Castle is a four-story, 28-room castle with towers, multiple boathouses, and even secret passageways used to spy on guests.

Dark Island also requires water access. Uncle Sam's Boat Tours does offer a Singer Castle Tour that will guide you through a few other islands. You can eventually stop on Dark Island, disembark, and take a tour of the castle.

There is a shuttle that runs from Schermerhorn Harbor to Singer Castle and back several times throughout the day as well, and you can dock on the island in a personal watercraft.

3. Boat Tours of the Thousand Islands

4. Charter a Fishing Guide

7. Deer Island and the Skull and Bones Society

From afar, the cabin on Deer Island may seem bland and ordinary, however, its secrets are vast and conspiracy theories shroud its name. The island is owned by and used as a retreat for members of the Skull and Bones Society. As a private island, you can't visit it, but you can get a good view of the island from a boat.

Over the years, as the island has been used less and less, it has become overgrown, and the cabin is said to be in a rough state, but new members of the Society are required to visit the island.

In the Area

If you have some extra time and want to see more of the area, there is always plenty to do. Both Jefferson and St. Lawrence counties have a host of state parks to visit. Many of them have visitor centers with educational activities, and almost all of them have trails to walk or hike and diverse wildlife to watch.

Black Lake is another prominent fishing spot in the area. If you have a passport, you can take a ride across the bridge to Canada, where there's even more to do, like an aquarium, helicopter tours, and scuba diving.
