Perhaps the question is about alternatives?
Ok I’ll go with that, thanks.
The obvious one is the decision between going through Hospitales or Pola de Allande. Lots of information on
this thread. Both routes meet at the high point, Puerto de Palo, but the ascent through Hospitales is more gradual and less steep. The thread I linked to gives a lot of opinions and comparisons.
The other major choice would be the Camiño Verde from Lugo. It gets a lot of good press, and I walked it a few years ago. I thought it was pleasant, but I don’t share the effusive praise of it that others lavish, but that may be because I got mixed up on my first day out of Lugo. I didn’t think Friol was a particularly interesting place, and that’s about the only place to spend the night on the day from Lugo. The main attraction of the Camiño Verde is that it avoids joining the Francés at Melide, but instead takes you to Sobrado dos Monxes on the Norte for the last few days into Santiago. The Sobrado monastery has recently been cleaned, and its new look is pretty beautiful compared to the dirty stone look of theh past. In terms of scenery and natural beauty, it is pretty similar, IMHO, to what you will find on the “main“ Primitivo.
There are at least three other little alternatives I can think of. By little I mean just a km or two to take you to some nice places.
One is to the monastery of Obona. It’s a well marked little turnoff before Campiello and takes you to an abandoned monastery where you can tramp around. Some
pictures. It doesn’t add more than a km or two to the day, so especially if people are only walking from Tineo to Campiello, this is a way to add a bit more.
Another, which I really recommend if you like ancient churches is to Soutomerille. Well marked on the day into Lugo. It has a window from pre-Roman times, and takes you on a beautiful path past chestnuts whose information panels told me they were more than 400 years old.
And finally, the Roman spa/worship spot/temple in
Santa Eulalia. This is definitely not to be missed, with the same caveat that it’s for those who love ancient architecture. This one is Roman. . It is about 14 km or so from Lugo, and you can visit it whether you take the Camiño Verde or have decided to stick with the Primitivo. (From Santa Eulalia, to get back to the Primitivo, you will pass very close to the 12C church of San Miguel de Bacurín - I have never found it open, but it has a beautiful doorway and is located in a peaceful spot).
I may be forgetting some others, but if my memory gets jogged, I’ll be back!
