The minimum distance to get a Camino certificate is 100 kilometers. I started my walk from Sarria, the most popular starting destination because it is about 110 kilometers away. I did it in 6 days because I wanted to take my time and enjoy the scenery along the way. It isn't anything like where I live and it reminded me of walking through the English countryside. You could also start walking from Porto, Portugal and meet the requirement. I was going to do that but that's when the pandemic threw a monkey wrench into everything. You buy a Camino passport and get it stamped at different places along the way to use as your proof of the walk when you arrive in Santiago. It was enjoyable but there is no way I would want to walk the entire Camino because I wouldn't want to be away from my wife for that long. If you ever want to give it a go give me a PM, I may want to tag along.
Here is a picture of where I live, taken from our terrace. We are in the province of Granada, where the Alhambra is and I can actually see the point from my house where the Moors landed to establish a kingdom in Spain then left from the same spot 750 years later.
Thank you, 110k would be doable. Beautiful spot you have, I lived on the beach for years much prefer the cliff views.
History is one reason I am looking forward to the trip, we get so little of Spain, The Moors or el Cid in our history.
You cook up your paella and I bring some good wine and we chat about the walk, maybe you do the Portugal route next time.
