Kosir's delivers an outstanding rafting adventure with guides who clearly love what they do. Names like Mike, Michael, Jason, Dillon, and Josh come up repeatedly, praised for balancing expert safety instruction with genuine fun and humor. First-timers especially appreciate the clear guidance and patient approach—one reviewer mentioned a guide checking in multiple times after a scary moment in the rapids. The Menominee and Peshtigo rivers offer different experiences with Class 4 and 5 rapids, and you'll often get to tackle the bigger sections twice. The owner's hands-on approach really stands out, even personally leading impromptu trips. Beyond the river, the campground creates a full experience. The on-site tavern gets love for its Friday fish fry and friendly bartenders, plus scenic river views while you eat. Reviewers talk about making this an annual tradition, which speaks volumes about the overall atmosphere and hospitality. One practical tip: bring serious bug spray, as the mosquitoes don't mess around. The consistent theme across reviews is staff who genuinely care about creating memorable experiences, whether you're a seasoned rafter or completely new to the sport.
An awesome adventure for us and our teenagers! Mike was an expert guide and kept us safe and entertained! It was empowering to have us conquer the rapids as a family ;) The other Mike took awesome pictures and they made a powerful team! Do not hesitate to book; we will be back!
