Petawawa River - One of Canada's classic wilderness whitewater canoe trips. Rapids progress in difficulty from CII to CIV ledge drops, with the final days in continuous CII. Beautiful campsites. It's a classic for good reason.
Barron River - Likely the most beautiful one day canoe trip in Algonquin Park - through the heart of the 70m deep Barron Canyon gorge. A flatwater trip with 3 easy portages. Suitable for all abilities.
