Running the Colorado River through Grand Canyon is a life-list trip for many people and a spectacular way to fully experience the beauty, solitude and unique environment of this natural wonder. The Colorado extends for 279 miles through Grand Canyon and attracts approximately 22,000 visitors per year, mostly on commercial raft trips. Floating the Colorado is allowed by permit only—obtained through the National Park Service or, on the lower section, the Haulapai Tribe.
This 279-mile stretch is wild, with no developments of any kind except for the off-the-grid store and lodge at Phantom Ranch mid-way through the trip. River trips involve primitive backcountry camping on river beaches and being blissfully removed from the bustle (and all electronics) of urban living.
Skill required:
The Colorado River through Grand Canyon encompasses 160 sets of rapids that are so unique and generally difficult to run that they have their own rating system. While other rivers follow a whitewater ratings system of I–V, Grand Canyon rapids are rated on a scale of 1-10. Unless you are traveling with people who are expert at running highly technical whitewater, plan to hire a commercial outfitter with seasoned guides.
Permits: A permit is included in all commercial trips. Private groups may apply for a permit through the park’s annual lottery system. For more information: nps.gov/grca/planyourvisit/weightedlottery
Season:
Most commercial trips run between May and October, with the peak demand months being June, July, and August. Go in fall or spring to avoid the crowds and triple-digit summer heat. Private trips often go in winter when more permits are available.
Outfitters:
All commercial outfitters authorized by Grand Canyon National Park to run trips are required to meet certain safety and environmental regulations. For a list of authorized outfitters, go to: nps.gov/grca/planyourvisit/river.
Since the Park Service only allows a fixed number of river visitors through Grand Canyon each year, spots on commercial trips are limited and typically fill at least one or two years in advance. Trip lengths and cost range from $100 for one day on the lower Colorado to $2,500 and up for a 21-day trip running the entire Grand Canyon. Modes of travel vary from motorized rafts to oar-powered boats to wooden dories.
