Bonnie Castle Resort offers 128 guest rooms

Rooms at Bonnie Castle Resort are spread across two buildings. The Channelside building overlooks the main shipping channel of the St. Lawrence River and adjoins our dining and conference facilities, while the St. Lawrence building overlooks the upper Alexandria Bay harbor and Bonnie Castle Marina.

We can accommodate a limited number of requests for adjoining rooms, and cots and cribs are available upon request. Please be aware that our hotel buildings are two stories, and the second floors are accessible by staircase only. If you will require first-floor accommodations, please let us know at the time of booking. All rooms are non-smoking. Limited pet-friendly rooms are available; please contact the Front Desk for availability at 315-482-4511. We look forward to hosting you!
