Described by many as the quintessential river trip on the Colorado River through Grand Canyon, this 18-day float trip is crammed with geology, botany, history, wildlife biology, ecology, and much more.

Traveling through Grand Canyon by river allows an unparalleled opportunity to view sites, ecosystems, and geologic structures not visible from the Rim or even by hiking, and to gain a more complete and holistic perspective of one of the grandest landscapes on Earth. Especially important are the numerous side canyons that are accessible only by river, each one fascinating and unique. Exploring these side canyons will help complete our picture and our understanding of this place.
