Miss Mariuxi Prieto is an excellent Guide, she was my guide and arranged to me a tour to "Isla Santay"a wonderful reserve located close to Guayaquil City in front of Guayas River. It was really good experience for me, because she knows about all the birds, animals species which exist in this Reserve and her conversation and explanation was so nice and clear. I loved this experience and learned a lot thanks to her.

I qualified her on 10/10 points as Biology and Guide professional.

I recommend her for future guides

Had a one day walking tour that was fabulous.  She made sure we saw what interested me and she is a naturalist guide so it wasn't simply looking at buildings.  She identified and explained everything from the naturalist perspective.  Very informative.  We covered a lot and I could not have been more pleased.

Mariuxi was outstanding!  She has outstanding command of the English language, deep knowlege of the entire island environment and enthusisam seldom seen in an experienced guide.  We could not have done better than having such a geat guide.
