Hi,
@chitra0828,
Welcome to the forum. You may be lucky and find someone here on the forum who has walked this. But for the most part we focus on the many caminos de Santiago that criss-cross Spain.
I think you are much more likely to get good info from the people who have walked this route and who have posted their GPS tracks on wikiloc.com
Find the best outdoor trails for mountain hiking treks, bike tour itineraries, MTB rides, and up to 80 activities. Discover the most beautiful places in the world, download GPS tracks and follow the top routes on a map. Record your own trail from the app, upload it and share it with the community.
If you’re not familiar with wikiloc, it is the most popular GPS app/website in Spain. It is an extremely friendly place, and I have frequently asked questions of the people who post the tracks. I inevitably get helpful responses very quickly. If you see a track on that list I linked to above that seems to be what you’re interested in doing, I would post a question in the comment section that is down on the bottom left part of every posted track. Doing it in Spanish will increase the chances that you will get good responses. Good luck!
