We decided to spend almost a week in Bordeaux, and so far the place is living up to my high expectations. Bordeaux combines so much of what we love about European cities — monumental architecture, great city planning, and lots of urban energy.

The city wraps around a smooth curve of the Garonne river and it is really loaded up with 19th century neo-classical architecture. Huge swaths of the city center have been pedestrianized, and the urban core has been designated a UNESCO World Heritage site. The streets are teeming with public art, street performances, and people enjoying it all.

Yesterday we took a train to the seaside town of Arcachon, where we rented bikes and rode out to a sand dune called the Dune de Pilat. Even knowing that this was the largest sand dune in Europe, I wasn’t really expecting all that much. I mean, what’s the big deal about a hill of sand between the beach and the shore? You see that in lots of beach areas.

But once we get there it was pretty incredible — a truly massive pile of sand with a life of its own. It apparently moves several meters a year, slowly swallowing up the forest inland. It’s already taken out some roads and buildings as well, including a hotel. After an arduous climb to the top we were rewarded with incredible views — and our first glimpse of the Atlantic Ocean since we left Boston!

Today we are embarking on another day trip out of town to encounter some of what Bordeaux is really known for — wine. I’m intrigued whether an all-day visit to wine country here will enhance my relationship to Bordeaux wines, which I have never really understood. This region produces the most celebrated and expensive wines in the world, yet I have rarely (including in the last three days here) tasted a Bordeaux wine that did not taste to me like licking a Band-Aid.

With two weeks left before we catch a flight from Paris to visit family and friends in the US, we left Barcelona to make a pass through Southwestern France. Our first stop was the spectacular medieval fortress town of Carcassonne. I’ve wanted to see Carcassonne since hearing my parents rave about it years ago.

This was just a two-night stay, and we spent a great deal of our time here doing some necessary travel planning. But we were also pretty immersed in the medieval ‘feel’ of the place since we stayed in a gorgeous hotel inside the walls of the hilltop fortress known as La Cité. Not only was the hotel itself fantastic, but they upgraded us to one of their best suites. With beautiful views of the castle and the ramparts of Carcassonne, our elegant living room made an ideal place to do our work and soak up the atmosphere. Next stop: Bordeaux.
