I loved the walk through Galicia - some of the best scenery around. It is very rural, lots of small farms, very green, lots of mysterious and misty places. You can feel the magic in the air.
Once we hit Sarria, things did get more crowded, but it wasn't nearly as bad as I thought it would be. We had a lot of solitude too. If we ended up walking by a big group, it was easy to take a break and let them move ahead or just keep walking when they took a break.
The advice not to stay at the end of the Bierley stages is a good one. Before Sarria, we sort of took it as it came, stopping when we wanted to, but after Sarria, we made a point to always stop mid-stage.
I did notice a change in energy and vibe on the Camino after we passed Sarria though - things did feel different. People didn't seem quite as friendly and open as before - both pilgrims and locals. I think it is just because there are so many more people after Sarria. It wasn't bad, per se, and no one was rude or anything, but I did notice a subtle change.
