Colorado River flowing through Grand Canyon National Park

The white water is excellent for rafting and the best thing to do if you plan a trip down the river here. Is to get as many days free as possible, hire a guide and set your course down the river. There are many waterfalls to pass by and walk around and some excellent hiking opportunities. [Image Source] Bonus Pic of the Patio below, a part of Deer Creek -- waterfalls along the river.
