My wife and I took the 'Full Day Basque Cities Tour from Bilbao in October 2017. Our driver/guide, Stephan, picked us up from the hotel at 8 o'clock in the morning and drove us to Vittoria where he picked up three more passengers. We had a walking tour of Vittoria with Stephan who provided comprehensive information at all places of interest. Stephan was a superb guide and driver during the whole trip. After Vittoria we visited Anana salt mine. This was a very informative visit for us to see how salt is obtained. It was surprising to hear that the simple technology being used today is the same technology used since Roman times. After the salt mine visited a number of towns on the way. The roads we were driven through were very picturesque under the autumn sun. We had a lunch including red and white wine included in the tour at a 16th century castle. After lunch Stephan drove us to Transporter Bridge which is the first bridge of its kind built in 1893. We crossed the river using the bridge. If you have a day to spend I would highly recommend this tour. The tour takes about 9 hours.
I took this tour on September 22nd. We were a group of eight, four English speakers and four Spanish speakers. Our guide was Stefan. He had the job of explaining details of the visited sights in English and in Spanish. He did the job perfectly for the entire 9 hours with non-stop enthusiasm and good humor. What Stefan knows about the Basque region and culture is amazing, possibly more than most other Basque people themselves. Our lunch in a former convent was great. Highest praise for this tour and our guide Stefan.
