Group Campground Information
Thousand Islands National Park encourages groups to experience outdoor camping in a natural environment.
Grenadier Island is for any groups organized for the pursuit of a common interest and larger than the party size that can be accommodated at a regular campsite. Access to the area is by boat only and the group is responsible for their own transportation.
For more group camping reservation information please contact the park office at (613) 923-5261.
