You have two options for the ferry to ibiza.We have big plans to drive at some point. We’re in the process of buying an Opus folding caravan ( like a trailer tent but better ). We get the ferry to St.Malo, and then drive to my mother in law ( stopping at a few sites on the way ) in Beziers which is close to Montpelier. Stay for a few days. Then drive down the coast. Barcelona is a couple of hours drive. Keep driving down and catch the ferry from a place I can’t remember. Stay for a week on a campsite and then do the journey in reverse. Reckon a three week holiday/adventure should be enough. But it will probably be 2024. That’s the plan anyway.
Barcelona or Dénia.
