Do NOT if at all possible miss sleeping in Ponte de Lima. It is one of my all time favorite camino towns anywhere. The municipal albergue according to Gronze is open.

It is a great location. Under the bridge within spitting distance of the muni is just a fantastic park along the river. It was a town I knew nothing about before I arrived and just loved it. I got there early. Left my backpack on the wall of the municipal. It didn't open unitl 3 or 4. Went to the park and loved it, had some lunch there that I had made the night before, went to the albergue, back to the park and then a really fun dinner on the other side of the bridge in the big town square. Just a great day!
