Mariuxi made my Galapagos trip phenomenal.  She has so much enthusiasm for the wildlife in the Galapagos that made every person excited too.  She is incredibly knowledgeable on the area, history, flora, fauna, and easily answers all of your questions.  On our cruise ship, she regularly joined in with the travellers and it felt like you were among family with Mariuxi.  I regularly looked for a guide to as a question about an animal in my book and Mariuxi was always available to answer your questions.  You can tell that she is passionate about her job and enjoyed talking with everyone.  Her zodiac landings on the islands were always the most popular among the guests.  Mariuxi is the best tour guide I have ever had (and I have travelled in over 60 countries)!
