I loved BOTH the
Coastal and the
Central on the Portuguese Way. Either choice would be fabulous.
Depending on how fast you walk, and if you actually have 14 full days, you could also consider the
Primitivo. It is a glorious mountain walk. Click on the link to see how it can be done in that time. We took 13 days to do it, and even had one rest day in Lugo.
If you are not worried about getting to SdC, you could also consider the amazing route on the
San Salvador, over the mountains from Leon to Oviedo, for 5-6 days, then continue on the Primitivo from Oviedo, (I recommend one day here to see the city), then 8 more days to Lugo, or however far you get. These days on the Primitivo, IMHO are the best anyway, especially if you have already walked from Melide to SdC where the Primitivo joins the French Way!
If you do the San Salvador, you can get the Salvadorana, a special certificate for completing the San Salvador, instead of the Compostela in Santiago! I thought that was kind of special!
I have lots of photos of my walks, if you click on the links, to help you decide. Happy planning and I wish you the best of journeys!
