What visitors say
The Yellow Butterfly Trading Post & Campground is a small RV and tent park set among large deciduous trees on Highway 17 between Sudbury and Sault Ste. Marie. Reviewers describe it as quiet, well organized and nicely laid out, with sites spaced for privacy.
The owners are the heart of the place. Travellers describe a warm welcome, help choosing a site that works for dogs and a trailer, and flexibility for late-season and after-hours arrivals. Sites sit on gravel pads with 30-amp water and electric, and a few reviewers mention full hookups, plus there's a dump station. The bathhouse is described as clean and adequate for the size of the park.
The trading post is a stop in itself, selling local crafts, clothing, jewellery and other gifts, and there's a snack bar with scooped ice cream. One long-time guest first came for the fishing, since it's central to several lakes and the Mississagi River. It works well as an overnight stop or for a longer, laid-back stay, and it's very dog-friendly.
The one recurring caveat is road noise from Highway 17, though a reviewer noted it's steady traffic rather than horns or engine brakes.
