Last year while in Yellowstone we did the 1 hour ride out of Mammoth Corrals. All of us are novice riders and I saw on the forum that 2 hours could be a lot for beginners. This worked out fine and we all enjoyed it. This year we will be by the Tower area, Canyon area and Grand Tetons. I see that they have corrals in Yellowstone at Tower and Canyon and both offer 1 hour rides. My wife gets slightly nervous and I heard that the trails at the Canyon and Tower are steeper than Mammoth. Is this really a concern? Are we better off riding in Yellowstone or somewhere in Grand Teton?
