Another day, another port, another stop with no definite plans. Again, Princess has laid on free buses to transfer us from the port in Getxo to the centre of Bilbao, not far from the Bilbao Guggenheim art gallery.

Top tip: Getxo port is miles away from Bilbao city centre. If your cruise line does not provide transfer buses, you may have to catch a local train from Getxo instead.

On the way we decide we should visit the picturesque old town. We also decide to do some geocaches on the way in the hope of finding our 700th, starting on the waterfront behind the gallery.

I have history of getting into trouble when visiting modern art galleries, so we don’t bother going into the Bilbao Guggenheim, opting instead for a walk along the waterfront. There are a couple of inventive geocaches along the way which makes the walk fun.

Eventually we arrive in the old town and head to the Plaza Nueva for a well-earned beer. As we imbibe a Mahou, a group of teenagers on a school trip begin an impromptu sports day. A few relay races are followed by several games of tug o’ war. The kids all look like they are having fun – and this is definitely not something you would ever see in Britain, let alone in the centre of the city.

We walk back towards the drop-off point and collect a few more geocaches on the way. The queue for the coaches to the ship are quite long, but move relatively quickly.

Because we’re back on ship long before sailing, we head down to the Goods Spirits bar and collect a drink (Prosecco for Lin) before going to afternoon tea. Afterwards we watch our departure from our balcony – the Spanish coast is quite impressive.
