I'd argue that the first day was my favorite day...we had a beautiful sunny day. We started late out of SJPP as a friend was taking a train that arrived around 8:45. We set out at 9:15 and made our hike up. we stopped at Orisson for a nice break where we grabbed a sandwich and enjoyed two beers. Then we headed on to Roncevalles. The views were excellent. The international friends we met were great. Roncevalles was nice...we were lucky and were on the top floor. Showered up, headed across the street to grab a meal and some (a lot) of Sangrias...just a great day.
I like the mountain stages I guess as my second favorite day was the hike from Astorga to el Acebo...such an awesome day. O'Cebreiro day was probably third...the views of the Pyrenees and the mountains of Spain are just fantastic.
I would love to own an albuergue on the Camino and my first choice would be Foncebadon. I am looking forward to getting back someday soon
