Well, actually, I walked a bit of it in September 2017. With friends I slid down the hill from Sant Pere de Rodes to Palau in the rain; the next day, with other friends I walked from Vilabertran to Les Forques, then alone to Anglès. Then off the official camí across the Ruta Serrallonga to the Susqueda dam, and there I stopped. I met no other pelegrins on the way.
This was my first long walk, first foreign walk, first solo walk, etc. My pack weighed 13 lbs at the start. I had only one pair of shoes, which was no problem. What I missed were a few extra pair of undies and a power thing to recharge my phone /camera. I ran out of battery every afternoon around 3 o'clock.
The signage was good. I had to check the GPS once or twice. I slept in one commercial youth hostel (Girona) and two small hotels (Calabuig and Anglès) at 40 or so euros per night. At Bonmati, they told me about the alberg, but I already had my reservation for the night.
Having dipped my toes in these waters, I am excited to go again, deeper, stronger, farther. There are things I forgot to do, things I had no opportunity for, things I didn't know.
