In the morning we drove the 1hr 15 journey to Colon, where the van has to go in a container in order to get shipped to Cartagena, Columbia. We had a Columbian guy who was shipping his vehicle with us, which made the process that much quicker and easier, but in essence we met the agent (Evergreen logistics) who sorted out the paper work, then we were escorted to the shipping yard, drove the van in, secured the container, then left. The whole thing took a few hours. We also managed to get a motorcyclist in our container, which reduced the price even further. For more detailed information of all this process, click here.
We had to pay $20usd between us all to get a taxi from the shipping yard to the bus station. There is an option of going by train to Panama City for $25usd, but we choose the $3usd air-conditioned bus. It was quite nice actually. 2 hours later, we in Panama and convinced by Abu, the motorcyclist, we went to his hostel, only to be informed there were no dorm or private rooms left. We ended up staying with the other couple (who's car we shipped with) and went out for dinner with them. The place we stayed was called Pensions y Corona on 36 y Peru. It was nice enough, but more importantly for us, it had really good wi-fi (a rarity when travelling sometimes).
