Took a half-day whitewater trip with my sons (12 &14) and had an absolute BLAST! Our guide, Riley, was fantastic; super encouraging to the boys (who had the front seats), pointed out a bald eagle, and passed on a ton of knowledge about the river, the area, and rafting. I lost my sunglasses trying to impress the boys - jumped into the river and forgot I had them on! - and Riley went back the next day to see if he could find them for me! This is an absolute can't miss activity while visiting Glacier!!!
