The Parc National du Bic is a nice place to stop, but all the provincial parks in Quebec are expensive, so be forewarned.
The Rioux family farm was established in the early 1900s, and the family lived here until the land was expropriated in the 1970s. The Rioux were apparently allowed to return each summer until 1981, which was the the date of their final expulsion, and probably when the park decided to turn their barn into a welcome center. I’m not sure other residents were extended the same courtesy.
Check the tides first, but walk along the beach if you can.
Some trails are only accessible at low tide.
