We highly recommend Gaston to be your tour guide. A very pleasant, knowledgeable individual who is fluent in English as well. We are so grateful as he did more than we could expect. We met him as soon we stepped off the cruise on 02/07/2019, while he had a clear plastic folder and printed my name on it while he drove slowly along the ship. Our arrival in the NP was early before the big buses with crowd arrived and allow us to enjoy the tranquility and stunning beauty of the NP with the birds.
