Kosir’s Rapid Rafts

Celebrating Over 40 Years of Whitewater Rafting Adventures

Wisconsin’s Original Whitewater Rafting

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! This means your whitewater adventure ends within walking distance from your car, camp site, the showerhouse and of course Rapids Resort where you can get a bite to eat or something to drink right after your trip.

Camping Peshtigo River

Located only steps away from our Peshtigo take-out and less than an hour from the Michigan border (which is the Menominee River) we have a large, wooded campground, complete with a clean, modern shower house. These campsites are roomy and come with picnic tables and fire pits. We have Larger Group Sites available, as well as sites with water and electric hook-ups for RV’s and trailers.

Fun and Friendly Staff

Here at Kosir’s Rapid Rafts we have a fun and friendly staff to make your rafting experience one of a kind. Our staff is knowledgeable about rafting, safety, kayaking, tubing, and also about the surrounding areas and rivers.


Tubing Peshtigo River

For those warm weather, low water Peshtigo days, Kosir’s Rapid Rafts offers tubing on the Peshtigo River below the whitewater stretch. The trip starts at our normal takeout at the Bridge and goes for about 45 minutes down the river to the first boat landing.


Kayaking Peshtigo River

Kosir’s Rapid Rafts now have sit-on-top, flat water kayaks available for rent. We start at boat landing where the tubing trips takeout and paddle two miles down the Peshtigo River and onto Caldron Falls Flowage to the next boat landing and back.

Beautiful, Relaxing Environment

These areas of Northeast Wisconsin are a must see! The beautiful scenery, woods, and waters will give you a feel of freedom and serenity. Use Kosir’s as your getaway escape or stress reliever.
