The port of Vigo has little to offer the visitor, consisting mainly of a long pedestrian shopping area, a couple of gardens, and a Corte Ingles department store.
The ship moors close to the town centre, and now that the new shopping centre has opened, you can use their lifts to get to the town level rather than hiking up the short but steep hill. So if you are planning on staying local, there is no real need to book a taxi.
Above the town is an old fort and gardens which gives you some nice views back over the river, but your ship will be hiding behind the port building, so although there is plenty to photograph from there, the ship will not be one of them.
It is a good port of call if you have had a few days at sea, and want to stretch your legs, of just to stroll through the shops. But if you want a full day, then I would seriously suggest checking the tours out again.
Hope you have a great cruise,
