Boldt Castle and the Boldt Yacht House
Boldt Castle on Heart Island is located near Alexandria Bay, NY in the famed 1000 Islands Region. Whether you are making an annual visit to see what’s new, looking for an affordable family vacation close to home or a couple seeking that romantic getaway, Boldt Castle and the Boldt Yacht House has something for you! In fact, the Castles’ legendary beauty nestled among the St Lawrence Rivers’ 1000 Islands will keep you returning year after year! The Thousand Islands Bridge Authority (TIBA) welcomes you to tour Boldt Castle to explore and experience an attraction like no other. Construction began on Boldt Castle in 1900 at the bidding of millionaire hotel magnate George C. Boldt as a tribute to his beloved wife Louise. Boldt Castle was designed as their summer dream home. A castle rivaling those of Europe, built on the St. Lawrence River, in the heart of the 1000 Islands. However it was not to be, Mrs. Boldt passed away suddenly just months before the completion of the castle. Mr. Boldt was inconsolable and immediately stopped all construction on Heart Island, leaving the property vacant for over seventy years… The Thousand Islands Bridge Authority (TIBA), who owns and operates Boldt Castle and the Boldt Yacht House, invite you to explore our website. Here you can glimpse what awaits you at Heart Island. A chance to experience the Boldt’s tragic love story and the magnificence of a bygone era…

Ultimate Heart of 1000 Islands tour is a MUST!
We really enjoyed our Ultimate tour. We are from Texas and had never heard of 1000 Islands region. We learned a lot from our tour guide, Liam. He is VERY knowledgeable about the area and gave lots of fact along with some fun!

Awesome Tour
We had a great day on this tour; Brad made the entire trip very interesting. The views were spectacular. The Boldt Castle was a highlight. We had our included lunch there at their picnic area. I highly recommend this tour.

Great use of time and money
Our tour was with Liam and Gary (the captain). Both were so much fun while at the same time being professional and knowledgeable. Felt super safe and the 5 hour tour went by quickly

Unforgettable Thousand Islands Cruise with My Wife
I recently visited the Thousand Islands with my wife, and our cruise through the region was truly exceptional. From the moment we boarded, the views were breathtaking peaceful waters, beautiful island scenery, and a relaxing atmosphere that made the entire experience feel special. The highlight of our trip was exploring Boldt Castle. The history, architecture, and romantic story behind it added so much depth to the visit. Walking through the castle together made the day even more memorable. We also stopped at a decommissioned lighthouse that has been transformed into a charming tourist attraction. Its preserved structure and panoramic views were absolutely worth the visit. This cruise gave us a unique blend of history, beauty, and tranquility. It’s an experience we’ll always remember, and I highly recommend it to anyone visiting the Thousand Islands region

How long does The Ultimate Heart of 1000 Islands Sightseeing Boat Tour take?

+
It holds an Outty Ranking of 86 out of 100, which we label "Exceptional". That score blends traveler sentiment (4.9/5 across 638 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable most highly reviewed in Clayton, and how flexible the cancellation terms are.

Is The Ultimate Heart of 1000 Islands Sightseeing Boat Tour suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 5-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book The Ultimate Heart of 1000 Islands Sightseeing Boat Tour?
+
Around 223 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Clayton can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Clayton and add a light layer if any part of the 5-hour experience runs outdoors or after sunset.

The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Clayton?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Clayton?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
