Relaxing, Beautiful Ride

Went on the Boldt Castle two nation tour. Very friendly captain and narrator. The price is very reasonable compared to going from Canadian side. We would definitely recommend this trip to all!!

A Must Do!

My husband and I had a great time on this trip. We were able to get an up close view of the Thousand Islands. Capt. Jack and Mike were great. They shared a lot of knowledge with us and even more laughs.

Rock Island Light Tour

This trip was well worth it. Our Captain Ron and Tour Guide Ken were both very friendly, knowledgeable, and interesting. The views that we had from this boat were breathtaking.
