We really enjoyed our stay at 1000 Islands Campground . It’s basically central to both Alexandria Bay and Clayton, so being right in the middle allowed us to plan activities along the river without having to worry about being gone too long from the dogs. It also has a market and ice cream shop right at the front of the park - you know we had to go try that!!

Boldt Castle was a real treat. On our Two Nations Tour , we stopped off here for about 90 minutes. I wish we had longer to explore the history. There is an app that you can use for an audio tour and enjoy some of the history of Heart Island and the castle. The castle has a very sad story.

There are a number of tour companies that will take you on a cruise of the St Lawrence River with a stop at Boldt Castle . The campground we’re staying in had negotiated a discount with Clayton Island Tours , so this is the one we purchased. We opted for a “Two Nations Tour” with lunch. The sandwich lunches were a good value for the price and our tour was well planned and narrated. The only criticism we have is the allotment of time at Boldt Castle was not quite enough to fully see the property.
