Padstow and Port Isaac. We travel to Padstow. Once the ecclesiastical capital of Cornwall, Padstow has many medieval buildings. In the afternoon, we visit Port Isaac, a traditional fishing village, home to the TV series Doc Martin starring Martin Clunes. This picturesque village has narrow winding streets lined with whitewashed cottages that head down to the harbour where you can watch local fishermen landing their daily catch of fish, crab and lobsters.
