I have been rafting quite a few times, and we enjoyed this one. We did the all-day trip, with a mostly calm scenic float, lunch on the river, and then an afternoon section with some white water. We did the 4-person "sport" raft, and that was more fun that a larger one.
If you are looking for gnarly rapids and a whole lot of action, doing this one especially later in the season is not going to excite you, and the you'll find the morning part a little boring. But the scenery is pretty, and there are some fun splashy bumps to get through in the afternoon, and everybody got wet.
What set this trip (and from this company) apart is the lunch they served on the river. They set up grills, and grilled up steak and chicken, along with chips and salsa, salad, PB&J sandwiches, and even veggie burgers. And they had it all set up and cooked inside of 30 minutes. It was a well-oiled machine.
The food was awesome. My GF called the steak the best she'd ever tasted (note to self...get better at grilling). I was amazed at how fast and how good the food was. Beats the heck out cold cuts and chips.
Our guide was AP, who was also the trip leader. AP was knowledgeable and funny, and he also knew his stuff on the river. A few of their guides are young and inexperienced, including one that accidentally dumped out our drinking water for the day, but AP handled it well. He made it a fun experience.
This is not really a "wilderness" experience, as a train track parallels the river the entire way, and no less than five or six trains passed us as we traveled. But the scenery was nice, and we even got to see some locals jump 40 feet off a bridge into the water beside us.
I wouldn't make a special trip to just come do this river. But if you are visiting Glacier, it's a fun day. And if you are going to do this trip, be sure to choose this company. You won't be sorry.
