We left Camping El Astral at Tordesillas around 1:00pm for what turned out to be around a 4.5 hour journey to the Port of Bilbao. Our crossing was the Cap Finistere at 10:30 on the Tuesday morning which we had been very fortunate to reserve given our original crossing on the Pont Aven had been cancelled due to her being in dry dock having a broken propellor fixed.
We were concerned about where to stay the Monday evening in order to guarantee arriving at the port for 09:00 the next day. Many campsites restrict vehicular movement between 12:00am and 08:00am.
We had read that at Bilbao, we would be able to check in the previous evening and then stay on the van portside overnight. This worked out really well. There was a bar / cafe open during part of the evening and early the next morning for breakfast. We had a decent nights sleep on dock side.
