We booked this tour at the Tourist Information office. The tour was in spanish. It left from the bus station. We went to the local area for harvesting clams. All the tourists donned rubber boots and rakes and we proceeded into the wet sand at low tide. The location was very close to the Torre del San Sadurnino. We were able to harvest clams and learn some of the different types and how this is done by local harvesters. After this, the bus took us to Pazo Baion for a tour of a BEAUTIFUL pazo (country house) and bodega (wine cellar). The tour was 12 euro, including both stops and wine tasting, a great value. The tour duration was closer to 3.5 hours, rather than the 2.5 hours they claimed, but no one seemed to complain!
