Best 60 minutes we have spent since arriving. Pedro is very knowledgeable about all the caves we visited. He is an excellent boat captain. He maneuvered his boat in areas that did not seem possible so we could get the greatest views of the caves. If you are planning a trip to the Algarve and want a tour of the caves, make sure you find aurora boat trips. Pedro and Mauro are excellent at what they do. Language is not a problem, they speak English, Portuguese, and French. Possibly more. I would recommend one of the early tours, it gets hot. Also, try to be the first in line and sit at the front. You can get better pictures. Thanks Pedro and Mauro for a great hour. And always remember, you don’t know history if you don’t know Portugal. When is comes to exploring and navigation…. We did it first.
