We are a couple, arriving at CTG at 12.30pm. With exit formalities, I expect to be outside the airport by about 1.15pm. We want to travel directly to Santa Marta and after 3 nights there, will be making our way back into Cartagena for the remainder of the trip. My question therefore is getting straight to SM. No doubt a cab would take us, but I expect that this would be fairly expensive (anyone know the likely cost?). Are there any vans or buses that do the run directly from the airport? Otherwise, I guess we will need to take the usual taxi into Cartagena and take the van/bus from there.
