There was only one couple on our trip who chose not to participate in the rafting but I'm not sure what they did instead. There is a spa, a winery and a movie memorabilia museum at Red Cliffs Lodge. There are also horseshoes, hiking trails and horseback riding. You can also book rappelling, ATV tours, Hummer tours, etc., and the vendors will pick you up at the lodge. But there is already a lot of time on your own built into the itinerary to do those kinds of activities.
