We did an afternoon rafting trip with Neil in late a July 2021 and it was fantastic! I'd recommend this over going into the park, although of course you can easily do both (I'd recommend the park in the morning, arrive early to get parking, then enjoy the rafting in the afternoon when it's warmer). I learned a ton from Neil about the area and the River in particular, in which he's worked for decades. Sometimes he sees big wildlife like elk and bears. He pointed out some raptors to us.
You park at Peak 6 outdoor store and meet Neil there. He drives up with the raft attached to his can and takes up up the road to a boat launch, then down the River about 9 miles, then back to Peak 6 in the van. You may get splashed but you won't get soaked, so you can bring a phone in a pocket. Definitely sunscreen up. Wear a hat that will stay on your head with a bit of a breeze. Bring some water because you'll be out for a couple of hours. The rapids are class 2, so not intense, and it's very relaxing and requires nothing of passengers. You'll have to step in the River for a few feet getting in and out, so wear shoes you can get a bit wet. Signing up can be a bit disorganized, Neil explained that's because he runs the business and is out on the water and internet is spotty in the area, but plan in advance and set it up and it will happen. read more
