Caminho de Santiago de Compostela you mean?
No. I have been there and have spent some time there. But I never got the free time or click to make (or join) a pilgramige. The Caminho passes near a place where I used to live. There is also more than one caminho, one coming from France, the other from Portugal, and probably others that I don’t know about.
What do I personally think about Santiago? Well, I haven’t tried it - altough I keep a strong connection with Fátima. When I went to Santiago it was by way of chance, I was visiting (and searching for) other catholic venues of interest which aren’t so well known and somewhat “alternative” to the main attraction. I liked it, off course - but I’m not the right person to comment since I was on a different search.
