Within reason, you can take just about whatever you wishafter all, youll be floating down the river, not carrying a big pack. That said, there is no point in packing way more than you need. So Id take two things: a decent three-season (or lighter) tent, and some sort of sun shade or awning.
How large is your group? If you have four, then REIs Hobitat 4 ($249) is an excellent choice in a large, cabin-style tent thats not too big or heavy (15 pounds). Quite raft-able. Also, it has good ventilation and is rugged enough to withstand a thunderstorm.
If you have two or three people and want something more compact, then take a look at Marmots Aeros 3P ($369). Its a backpacking tent with room for three. Its very light (six pounds) and super well-ventilated, as the entire canopy is mesh. And of course it has a full-coverage rain fly in case the skies open on you.
Or, for two people, theres Mountain Hardwears Meridian 2 ($200), a nice, basic backpacker that weighs less than five pounds, has lots of ventilation, and is weathertight.
I think for meals and standing around admiring the view, a sun shade or rain shelter of some sort is in order. MSR makes a big one called the Parawing 19 ($250) that can keep eight or nine people out of the weather. It sets up with two poles and multiple tie-downs and can be configured in a variety of different ways. Or, for something a little more compact, Keltys Sunshade ($150) covers about 50 square feetenough for a half-dozen people. Its a popular item on Grand Canyon trips.
Sounds like fun. Send us some pictures!
