Mari is the best tour guide we have ever had. She is extremely knowledgeable about island history, animals and plants. She provided the right amount of information so we learned but didn't become overwhelmed. The best part abouy Mari is not this wealth of knowledge, but her passion and enthusiasm towards the animals and nature, in general. Every sea lion, iguana, bird, turtle or fish was exciting to her, so it was exciting to us. Her joy is contagious! See always had her eyes open, looking to show you something interesting. She when above and beyond. She also took safety very seriously. You would always leave her tour smiling. We would do whatever we could to make sure we were on a tour with Mari, instead of other naturalists. She was so much better than any others. Her English is very good. She has a vast vocabulary. I wish she could be our tour guide on all future trips. She is top notch.
