We did it in June 2023. We first walked the CF from SJPdP. We scheduled our flight back to USA out of Porto because we wanted to walk the CP costal route since we had never travelled that route. We had walked the CP central in 2017, so we started in Vigo rather then Santiago. We did not collect any stamps and never had a problem staying in the albergue's. The only thing that we really missed was the opportunity to spend more than one day with other pilgrims we met since we were heading in the opposite direction. As mentioned above - WisePilgrim app will keep moving in the correct direction. You will notice there are stretches where there are 2 path - one close to the ocean and the other a little in-land. We did some of both, but decided we liked to stick close to the water whenever there was a choice. We leave on Sept. 4 to walk the del Norte - maybe we will cross paths.
