Basin is popular for so many reasons - proximity to Red Lodge, paved roads all the way, a wild and crazy small river, great hikes literally across the street, a well laid out and logical arrangement of sites and the knowledge that a small group of enthusiasts will always be there to whoop it up with you. It might seem harsh to only give it three stars, but it’s just that much more crowded, noisy (the road is right next to the sites) and hemmed in compared to Cascade Campground, which spreads out down where the paved road ends.
