I did a half-day Brown's Canyon trip, and had such a great time that I went back for a half-day Numbers trip. The whitewater was great, as was the equipment and the guide on both days.
I was staying with friends in Salida and didn't have a car, so I asked if I could catch a ride with staff in the morning, and they were nice enough to pick me up both times! (Then after the rafting I caught a ride back with other customers.)
I would highly recommend this very professional outfit for your exciting rafting adventures in Colorado.
