Having guided since 1982 in the Grand Canyon, I can assure you that it is very common to find single travelers on these amazing trips.  Also, there is never any single supplement fees or charges!  People who come by themselves find that there are some great advantages to traveling alone on a multiday rafting trip.  Number 1 being,  you never have to discuss with your traveling companion where you might camp each evenig in camp.  Those "I want it my way" discussions such as,  "I dont want to be by the river" or "that camp site is too close to the path to the porta potty" just dont come up.  The I want to do the 3 mile hike all the way to the waterfall and other wants to stay on the beach and sunbath with you, issues are non-existant as well. Singles find that it is easy to get to know the guides faster, as they have the time to go and socialize more with them, often learning those more entertaining and not told in large groups stories.

River trips quickly become a small tribe of people working together to make the trip a good experience for the whole.  Whether it is giving someone a helping hand on a hike, making a dinner together as a group on a night when for some reason the rafts got to camp late, putting up a tarp together or helping each other with a tent in a rainstorm, the small pod of river adventures quickly bonds and often become friends for life. Singles excell in this kind of situation I have found.   Take lots of photos and keep a good jounal and you may find that many of your friends will want to join you the next time, but it will be a diffrent experience.  Check out this site http://www.ehow.com/how_4511365_book-grand-canyon-raft-trip.html for more information on how to go about finding a Grand Canyon rafting trip.
