Most Idaho rafting trips are appropriate for children as young as 7 years, but more experienced adventurers will not be disappointed with long stretches of Class III whitewater and abundant hiking and fishing opportunities on all of our Idaho rafting trips. So, it should come as no surprise that OARS offers a wide variety of river trips for first-timers, intermediate, and experienced paddlers. Idaho has more miles of whitewater than any other state in the country.
