We visited Tavira recently by train whilst staying nearby in Faro, and were lucky enough to find that Maria's Tuk Tuk was free to do a tour. We took the 1 hour tour which took us around the town, to the salt plains (and flamingos!) and to see where you could take a ferry across the water to a nearby beach. We were told some history,, shown many interesting buildings and had a chance to take some photos at a couple of locations. The young guide was lovely. Happy to recommend this tour if you visit, but you may wish to try and pre-book. A nice touch was you were given a couple of books to keep with all the highlights you'd been shown on the tour.
