Kosir’s Rapid Rafts

Celebrating Over 40 Years of Whitewater Rafting Adventures!

Kosir’s Rapid Rafts was Wisconsin’s first professional whitewater rafting outfitter with operations on both the “Roaring Rapids” section of the Peshtigo River and the mighty “Piers Gorge” section of the Menominee River. These are the most exciting and challenging whitewater rafting trips in Northern Wisconsin. We are the only Midwest Peshtigo River outfitter based on the river’s edge at the end of the famous “Roaring Rapids” section of the Peshtigo River. Our convenient and private landing is located at our company headquarters and campground We have a prime location on the shore of the Peshtigo River at the end of the “Roaring Rapids” section of the Peshtigo River. This section is one of the longest stretches of continuous whitewater in Wisconsin and the Midwest.


Peshtigo River Whitewater Rafting Spring

Peshtigo Spring Run-Off Trips Class III – IV whitewater rafting trips run from early April to mid-May, when the water is chilly but very fast and exciting. Spring whitewater rafting trips include Farmer John style wetsuits and booties along with helmets, life jackets and paddles, and are run in four, six and eight place rafts. On spring trips it is very important to advise everyone in your group to bring an unlined windbreaker, wool or synthetic pullover sweater and wool socks. Also, a polypropylene long underwear top is an excellent addition to your cold weather gear. Check in time is one hour before scheduled whitewater rafting trip time. Spring trips are very popular because the die-hard rafters like to go when the water is the highest. Snow melt coupled with spring thaws usually makes April and May the best for big water whitewater rafting in Wisconsin. It may be chilly, but you will keep warm with the provided wetsuit and the excitement.

Peshtigo River Whitewater Rafting Summer

Peshtigo Summer Trips Class III Starting mid-May and running through September, for beginners and intermediates, whitewater rafting trips are run in one, two, three and four place rafts. Water conditions change daily and the actual size of the boat will be determined on the day of the your whitewater rafting trip. The trip covers about five miles of the most exciting white water in the entire Midwest. We provide helmets, life jackets, paddles, and transportation to the put-in point on the river. We are located right on the river, so all trips end at Rapid Rafts headquarters, where rafters can change clothes and relax. Check in time is 30 minutes before scheduled whitewater rafting trip time. Ask about our special group discounts offered for qualified scout, youth and church groups. Summer trips are for the entire family. This whitewater rafting trip is the same stretch of river that our spring trip covers but the weather is much warmer and so is the water. The river level may be lower but the thrill is always there.

Funyaking on the Peshtigo River

Funyaks are the most popular way to experience whitewater rafting on the Peshtigo River. A Funyak is a one-person inflatable raft. You paddle the Funyak with a two bladed kayak paddle and they are self-bailing so you’ll never need to empty out the water. Funyaks are perfect for any skill level including beginners. In fact they are easier to learn how to paddle than a raft. These are a thrill in higher water and great for lower water levels, with greater maneuverability. Because you are alone in the raft you have more control, you don’t have to try to coordinate your paddling skills with others in the raft. Being alone also means there is less weight in the raft, which makes it easier to move around or off obstacles if you should encounter some. Just keep in mind that even though you are alone in the raft you are never alone on the river, we always have staff on hand with every whitewater rafting trip happy to assist you. For more enjoyment in low water or a bigger thrill in high water try a “Funyak” the next time you raft with Kosir’s Rapid Rafts.
