Vigo was established with a foundation in local fishing, and over time, this has proven to be a wise decision — today, the city boasts one of the largest seaports in Spain. A cruise to Vigo is an excellent way to visit this city. Enjoy a walk through El Castro, the 17th-century fortress overlooking the port, and stroll through gardens as lovely as the sea views. From Vigo, you can explore Santiago de Compostela, the capital city of Spain’s Galicia region, whose “Old Town” neighborhood was declared a UNESCO World Heritage Site in 1985.
