Probably the best one day commercial rafting trip out there, but not for the faint hearted. Rapids are difficult with one portage. Need to pass two swim tests at beginning of Gore Canyon. One swim test is swimming under boat, the other one is Class 2 rapid swim. They will fail you, if so you walk 3 miles back to Kremmling. Brett, the guide knew his stuff and placed the raft where it needed to be. Highly recommend Liquid Descent for Gore Canyon which is absolutely beautiful. Enjoy the scenery while you are there
