Tour Duration: Approximately 5.25 hours. Your destination today, the province of Pontevedra, lies to the south of Vigo. You'll drive to the beautiful medieval walled city of Tui, located on a hill next to the Portuguese border on the River Mino. Visit Tui's imposing cathedral built in the 12th century and later converted into a battlement-studded fortress -- the logical response to the frequent invasions endured by the town. Its tower forms a magnificent balcony over the river and, from it, the city appears to be terraced out of the hill. A tasting of locally produced wines awaits you at the beautiful Parador (state-owned hotel), which is a reproduction of a rural Galician country house sat among mountains and rivers. Follow the border to El Rosal -- the part of the province where the majority of the Ribeiro wine is made -- and continue to the coastal city of Bayona. See the Castle of Montreal. This old fortress is now the site of a Parador, but retains its original outer walls with its battlements and sentry walks, clock tower and prince's tower. Relax over some delicious tapas and sample more of the fabulous wines of Galicia. NOTES: This is an active excursion involving a lot of walking. Some stairs and cobblestone walk to negotiate to access the balcony at the Cathedral in Tui. There are no rest stops on the drive.
