Stop at the Microbrasserie du Lac-Saint-Jean for a bite to eat or a pint, or enjoy a sundae from the adjacent Bar Laitier. We tried to find the beach, alas, it's all camp grounds.

Rather than riding through town, one can cross several of the dams that hold back the water in Lac-Saint-Jean and end up crossing Le Grand Décharge on a pontoon boat (frequent service). The central (power station) provides electricity to the aluminum smelters in the region.
