Fishing and Diving

Bonnie Castle is a sportsman’s dream location! With an onsite boat ramp and dockage available (for a fee), our location puts you on top of the fishing action in no time! Not to mention, the St. Lawrence River was recently rated the top smallmouth fishing destination in the United States. Give us a call for packages and guide referrals too.

For the SCUBA divers it’s no secret that we’re located in the middle of some of the best freshwater SCUBA diving anywhere, but did you know about the dive platform right off Bonnie Castle for guests and our dive operator partners? That’s right: either bring your own gear or use one of the top local divemasters to help plan your day exploring wrecks you can see from your Riverview room.
