Last week we took the river raft trip from Glen Canyon Dam to Lees ferry. It was a great experience. Booking was easy, the directions were good, the trip was well organized, and we thoroughly enjoyed the trip. We took the morning trip so it was a little cold in the morning - wish I would have taken a sweatshirt but a hour into the ride, it was getting hot. By the end, it was very hot! Riding through the canyon is great - the red canyon walls are beautiful. The ride back is probably an hour long but the scenery is nice. So assuming that you are awake, you will have something to do. We ordered lunch through Colorado River Discovery. The vegetarian option, a black bean wrap, was tasty.
