We caught lots of browns (and about 10% rainbows) over three days -- I probably averaged about 10 fish a day during the last three annual trips we took. This is a photo of a sample canyon -- although there are many types of rock formations, the river runs through a canyon for the first 2 and 1/2 days of the float. It opens up into meadows after that. Part of the fun is the sheer variety of water you face, and the ever-changing hatches as you work your way down-river and through different hatches and different parts of the day. We also go in early June, and it is HOT!
