Reviews

“Loved the Boat Tour”

“Our family took the boat tour and loved it so much that we will be back to take the tour to explore the castle next time! Friendly staff and very informative. Overall it was a wonderful experience.”

“A Pleasant, One-Hour Trip”

“It was a really amazing experience to 1000 Islands by Rockport boat line. Such a pleasant 1 hr trip around this island.”

“Would Definitely Go On This Cruise Again!”

“I would 100% recommend this cruise if you are planning to visit 1000 islands! I went for the 2 hour cruise and I thoroughly enjoyed it. There was a lot of sitting space and the organizers try not to make it congested. The boat we were on consisted of three levels, each providing a really nice view and I felt as though the tour was informative and detailed, which I liked! The boat enters the American borders for a little bit! The boat passes a historic castle, and some cruises stop at that location for two hours so that passengers can visit it! I would definitely go on this cruise again!”
