The best season for white-water rafting at the Grand Canyon is April through October, when temperatures are moderate and there is not much precipitation. If you decide to raft in the colder months of October through February when temperatures can drop and rain and snow are more likely, be sure to wear warmer, water-resistant clothing, such as a dry suit, rubber bib pants and gloves. Shoulder season--March and September--can be a good time to find discounted rates.
The Grand Canyon was carved more than 6 million years ago by the Colorado River, which streams through the canyon for 280 miles. Segments of the Colorado are available for white-water rafting trips lasting three to 19 days, the latter of which is the length of time it takes to raft the entire stretch of the Colorado through the canyon. These rafting excursions use motorized rafts and rowing or paddle rafts and can include opportunities for hiking and swimming. There are also floating trips that have no rapids, but these are not available in the park.
Rafting the Grand Canyon offers spectacular views and waterfalls. There are bighorn sheep, blue herons, eagles, hawks, cactus, wildflowers, mule deer, coyotes and other wildlife in the area. April is the best time to see wildflowers in bloom. Rafters may also see Native American ruins. Note that to get to the Colorado River, travelers must either hike, boat or take a mule down the canyon.
Summer is the most crowded time for rafting the Grand Canyon. Temperatures can climb into triple digits in June and July. In July and August, be prepared for summer thunderstorms.
Many tours include meals and gear in their package pricing. Check ahead to get a list of what you should bring. Make sure you're healthy enough for strenuous exercise--rafting can be hard work, especially if you choose a paddling option. Clear the activity with your doctor if you have any health concerns. Children under 7 should not participate. Different outfitters have different rules--be sure you know them. The water can get rough, so be prepared for a hair-raising and exciting ride.
Take care when rafting in winter as the days grow shorter. Trips down the river may take longer because of loss of daylight. The low temperatures in winter can be difficult to manage, so be sure to dress accordingly and try to keep dry and warm.
The sun can be brutal while on the water, in summer and in winter, so wear plenty of sunscreen year-round.
