We took a tour of the city for $40. This included Gatun Locks, the cathedral, a Hindu temple, and many other sited. Avoid the crowds of tour operators at the mini-mall area near the pier. These tours start at $40 for a trip to the locks and add other stops for more money. We found George out by the street. He patiently waited at the locks while we watched several ships pass through. He then took us on a leisurely tour of the city. It still left us enough time to shop for souvenirs. It was one of the highlights of our cruise.
