2 Nations Tour - A very nice tour of the St Lawrence River and Boldt Castle. Our guide was very knowledgeable of the history of the islands, prominent families and waterways. Very entertaining! The self tour of Boldt Castle and the grounds were amazing! Absolutely beautiful. A must see if in the area.

The Thousand Islands... - The Thousand Islands really must be seen by boat to be fully appreciated. Liam was charming and his narration was engaging. On a small boat, we were able to venture close to the islands that were the subject of his commentary. We were very glad to have taken this tour. It is necessary to buy the Boldt Castle tour tickets separately unless you want to stand on the dock at Heart Island for an hour and a half. Viator should tell customers this or the tickets should be included.

An amazing boat Tour to Boldt Castle - We had an amazing experience. This was a memorial trip to remember my 10 year old sons, father’s death 2 years prior. The St Lawrence was his absolute favorite place to vacation and fish. The tour guide and captain were so kind and patient. Visiting Boldt castle was beautiful. Thank you for the memories. We will definitely be returning for some other tours!

Bucket list item! - This place is absolutely stunning! They have done so much to restore parts of the castle and maintain the grounds. Give yourself at least 2 hours to see everything in and around the castle. They have an app with an audio tour to guide you around the property. You can pay a small fee ($3) and take a short boat ride to the chart house (?) Just across the water from the castle. Be sure to dress for the weather as everything is completely open all around the property. *Chilly in May with 40s and 50s. Depending on the charter boat company's location, it may take about an hour to get to the castle. Dress warmly if you are traveling in the off-season, as it is quite chilly on the boat.

Questioning Viator Tours? - Upon arriving at the departure point, we were told our voucher/ticket was no good. Director said, "That company often mirrors our description of this Two Nations, Boldt Castle Tour, but those tickets are not for this tour." We were so disappointed, had to go to the ticket window and purchase two tickets to be allowed on board. In planning tours for my spring and summer travel, I am hesitant to use Viator.
