The boat is a great option. Total change of scenery and, if you have the same pilot, a very informative journey. The last 28km is doable in one day, depending on tide times. Mine left at 9h30 and I arrived in Padron in the middle of market day. Overwhelmingly noisy after so many kilometers sĂłlo, but a great place to top up fresh fruit and cheese. I broke the journey around half way at O Faramello, leaving just 13.5 km for a shorter stroll into Santiago de Compostela.
