Port-au-Persil is the postcard side of Saint-Siméon: a tiny hamlet pressed into a cove, with a white church, a few houses, and rounded rocks running down to the St. Lawrence. It is small enough to see quickly, but pretty enough that rushing feels wrong.
The point is the setting, not a checklist. Walk down to the shore, look back at the church and houses, and let the river do most of the work.
