I'd want a minimum of a tarp under me due to the goose turds on some of those islands but would prefer a basic tent setup. If the mosquitos are out, they can be miserable. As others have stated, learn the river a bit if you can. A good guide you can find at the library is
https://paddlealberta.org/product/ma...erta-paddlers/. Photocopy the pages you need for the Bow and go from there. Check in with the local fly shops as well. They will have the current beta on river flows and hazards. Sounds like a sweet trip!
