Due to the train strike in France it did not go so smoothly today, but luckily I was so close to the Spanish border that using local buses and small private train I am now in Burgos. Here I realized that the youth hostel I had reserved was 100 km away from Burgos, but no problem I found a pension from the city center. So ready for the new adventures.
Yesterday in Biarritz was relaxing, did long walk through the forest to the Atlantic Coast and wandered along the coast for hours just listening to the sound of waves and feeling the breeze. I did carry my swimming suit, but the excuse not to swim was that nobody was looking after my bag. My sightseeing was a great aquarium. Enjoyed watching the life of fishes and other underwater life.
