Hi Alissa, We mostly did the Invierno last June. You can check out my Live from the Camino thread
here. Some caveats about our walk: We were recovering from Covid when we started and skipped the first stage to Las Medulas. We also ended up having to take a second rest day and took the train from San Clodio to Monforte de Lemos. My husband also injured his knee so we were doing short stages and we took a cab from Diomondi to the top of the river canyon before Chantada to avoid the big up and down to the Rio Minho.
I made little guide before we left with our planned route based on the info I got from Gronze and from the Forum Guide (which is very good) and other sources. It is
here. I updated it with notes about the walk when I posted it last August. We had a phone with us and used WhatsApp a lot, but we really tried to stay as tech free as we could so the paper guide was handy. I could only post a .pdf, so if you want the Word version which you can revise -- message me your email and I'll send it to you.
All this is to say that there are plenty of options along the route and you can make it work even under adverse conditions! And it is a very beautiful route. We walked the Primitivo in 2015. Regarding difficulty, I would say the two routes are comparable. The lodging options are a combo of pensions and albergues. We relied on the info in Gronze for contacts -- it was great. We never had issues and did not book more than a day ahead at most. The advice to contact places either the day before or morning of the day you will arrive is good e3ven if you aren't booking -- these places are not busy and even the albergues can be used for other purposes. You don't need to worry about this in Galicia because the albergues are staffed by paid folks.
Regarding Manuel Mar and bag transport. We used Manuel. He was very reasonable and reliable but he doesn't always communicate the complete info you might like the first time -- but he always responds to your WhatsApp messages. He will transport your bag from Ponferrada to Santiago. We found that he does not like email and responds much better to WhatsApp. If you want to use his service for the entire route, he will ask your itinerary and where you are staying in advance. He has a bag tag system that will ask you to fill in the entire itinerary on the tag. Don't worry about this. We changed our itinerary several times and were able to easily WhatsApp him and make the changes. Don't feel that you must stick to whatever planned itinerary you give him initially.
Also the Xunta albergues in Galicia
do not accept bag transport. Manuel will deliver your pack to a bar or restaurant in the town where he has made prior arrangements. We did not realize this and had to hunt down our bags the first time this happened. (He told us that the plan would work but not that he counldn't leave our bag at the albergue!) And one time the place he used did not open early enough for us. (We left our packs at a different bar and WhatsApped him the location -- no problem). So if you plan to stay in a Xunta albergue just make sure to pin him down in advance about where he will deliver your bag. I really don't want to make it sound like he is not reliable -- he is. His is just a very small operation and these were very minor glitches.
I will add that we ran into a French pilgrim who was using Correros -- they were charging alot -- I think I remember 25 euros a day (last summer Manueal was charging 6 euros per day, per pack). And they do not transport on Sunday. After we talked to her, she switched to Manuel for the rest of her walk!
Buen Camino,
LizB
