I have just applied for Laodore and Yampa canyon. Assuming it is not high water is it possible to take 4-5 year old kids? Which canyon is better for kids? In the few rapids, can they walk around? I have heard of people taking kids but not sure which canyon. The kids have done several raft trips but I don't want to expose them to any serious or extended whitewater. Any info on the canyons or experience with family rafting would be greatly appreciated.
