Was the most amazing declaration of LOVE…..if I was going to make ONE recommendation, it would be for the Island Visit to be longer. 1 1/2hrs is just not enough. The Boat tour and Tour Guide along with His, Knowledge, Personality and attention to detail was remarkable

We had a tour scheduled for 10:00 AM on June 4th, but it was cancelled because there were no other participants, so we missed out on the tour. Having traveled all the way from New York City, we were incredibly upset and dumbfounded.

Beautiful day on the water. Boldt Castle definitely worth visiting. Narration added to the trip. Enjoyed the smaller boat and more relaxed vibe.

Rob was a great tour guide and our captain let a small boy drive for awhile which was very special. We saw a number of eagles and osprey. A beautiful day!

It was a truly fantastic sightseeing experience. At first, the islands were obscured by a layer of mist hovering over the water; however, 40 minutes later—once the fog had completely lifted—we were treated to an indescribably beautiful spectacle of islands that was nothing short of magnificent and mesmerizing. Accompanied by our guide's excellent and wholehearted commentary, we enjoyed a truly delightful journey.

We booked this boat and castle tour when visiting friends near Clayton in NY. There were a few options, and this tour seemed to offer what we were looking for at a very reasonable price. The boat guide was wonderful, full of information about the area and fun stories. I would suggest sitting close to the boat guide as sometimes it was hard to hear him with all of the river and boat noise. The castle tour was also great, and as someone with some mobility issues, I appreciated the option of riding a golf cart up the hill to the castle, and the fact that there is an elevator in the castle.
