I travelled by bus all the way from Spain to France, which was only a 3.5 hour drive. France and Spain share a border, so travelling is very easy betwen these countries--especially when travelling from Barcelona (where I am, now) because of how close this city is to France.
The furthest I have travelled is when I went this week to the south of France. I have also traveled to a small beach town and the volcanic zone, which are both two hours away from Barcelona. All three trips have been so great, I can't even pick a favorite! Oh, and I travelled over 3000 miles from the United States to Europe!
I took a big bus and used public transportation in Barcelona, such as the metro, which is similar to a train. Barcelona has amazing public transportation, meaning that many people here do not even own a car.
The most interesting places I visited this week were the cities of Carcassonne and Coulliure. The first of these had an incredible castle; the other was a beautiful town situated on the ocean.
