Fernie has a selection of companies to choose from if you want to go rafting. There's everything from full-day whitewater rapids to lazy floats down the river. We opted for a three hour river float on the last afternoon we were there. The weather turned on us and it started to rain, but we went anyway. It tuned out to be worth it, (the rain only lasted a few minutes) but the extra water made the river a little choppier than usual. Definitely still worth it, plus there were plenty of snacks.
