Fractions Rafting on the Arkansas River
Fractions is a classic half-day Colorado whitewater trip: continuous, fun Class III rapids under the 14,000-foot Collegiate Peaks. You’ll paddle through rapids like the Miracle Mile, Beaver Falls and House Rock, and weave through the boulder mazes and rock gardens that define this section of the Arkansas River.
It’s a great fit for families and first-timers ages 8 and up, with plenty of excitement for experienced rafters too. Fractions leaves from both our Aspen and Twin Lakes shops
Any trip can be made private and customized for your group.
Frequently Asked Questions
No. Our Adventurous trips are Class III, intermediate whitewater, and suit first-time rafters who want a real whitewater thrill. You’ll need to be in good physical condition, follow your guide’s instructions and paddle through the rapids.
Kids 8 and up can join most Adventurous (Class III) trips, depending on water levels. Everyone needs to be in good physical condition and able to paddle. Check the Trip Details on each trip page for its minimum age.
Length and lunch. Half-day trips, like the Upper Roaring Fork, Fractions and Shoshone, run the most exciting stretch of whitewater in about two hours on the river, with a snack at the end. Full-day trips, like Browns Canyon, spend about four hours on the river, cover a longer scenic stretch and include a riverside lunch.
Any time in the main season, May through Labor Day. Early in the season, late May to early June, the water is higher and faster. From mid June through August the flows are steadier. We move our Class III trips between rivers to follow the best flows, so check each trip’s season in its Trip Details.
Fractions is a half day of Class III rapids for ages 8 and up. Browns Canyon is a full day of Class III whitewater with a riverside lunch, also for ages 8 and up. Numbers is a half day of Class IV whitewater for ages 15 and up who can swim.
Continuous Class III rapids, including the Miracle Mile, Beaver Falls and House Rock, with boulder mazes and rock gardens in between, under the 14,000-foot Collegiate Peaks. Fractions runs from May to August 15; after that, our half-day trips move to Shoshone on the Colorado River.
What’s Included
The raft trip and transportation to the river, a helmet, life jacket and paddle, splash gear, booties, a wetsuit when the water is cold, and food as listed in Trip Details. Trip photos aren’t included, but you can buy them online after your trip.
What to Wear Rafting
We suggest wearing quick drying clothing such as non-cotton shorts and t-shirt or bathing suit. Be sure to bring waterproof sunscreen (you will be rafting at 9,000 feet where the sun is intense!), sunglasses with a retaining device, and comfortable walking shoes. We will provide you with neoprene booties, so your shoes will not be going in the river. Bring a towel and a change of clothes for the ride home.
Our shuttles will act as your mobile locker room. Everything that is not going on the water will stay on the van! It will be manned at all times or locked throughout your voyage to ensure your stuff will be there upon your return.
