The video I watched was by Jessica ('Dixie') Hill, an Alabaman who posts on YouTube under the moniker Homemade Wanderlust. She has hiked and produced videos on the Triple Crown of American trails, not only the Appalachian, but the Pacific Crest and the Continental Divide trails. Her videos tend to be personal stories, with a lot of her talking and sharing stories as she walks along the trail. I've watched quite a few of hers now, so I've gotten to know her personally and for that reason I enjoyed her video on the Camino where she took her sister along to hike the pilgrimage.
But I already new about the Camino from other reading, and from friends who have walked it. It is an ancient 500 mile pilgrimage route across northern Spain, dating back to the beginning of Christianity, and popular during the Middle Ages. St. James is said to be buried where the cathedral of Santiago de Compostella was built, so that is the destination of the pilgrimage.

There are actually several different routes to these trails, but the most popular today is the Camino Frances, starting at Saint-Jean-Pied-da-Port in extreme southwest France. This is not your typical North American 'hiking trail', you can easily walk side by side, and there are villages with hostels every few miles, so there is no need to carry either a tent, a stove, or food beyond your daily snacks and some water. It's a wide, relatively flat gravel pathway often running beside modern highways (the pilgrimage path was there first), a far cry from the Appalachian Trail! It would be a walk in the park for serious long distance hikers!
The best description I've read of it was in a series of blog posts by 'The Chouters', an American full-time RVing couple (now hiding in a quiet campground in France) who walked it in June 2019. Their description is more nuanced than others, and Steven is an outstanding photographer. (I also followed their trip to Alaska a few years ago). You can easily scan through a few of their blog posts and get a good sense of 'The Way of St. James'.

I personally think this reflects a bad misunderstanding of what the Camino is, and poor advance research. If you check the HikerJournals website for example, you can find 20-30 hiker journals of this walk for each of the past few years. If you google .Camino de Santiago you will also quickly discover the Camino privitino, a route which does follow a narrow trail away from roads through the mountains and which might require you to carry a tent and food.
The Wikipedia article on the Camino is actually quite good, giving a good introduction to the history of this ancient pilgrimage. It's easy to do advance research before tackling this pilgrimage.
And you can always do the walk in your mind today while we're all isolated and sitting at home!
