Elvin was hands down the best tour guide I have ever had, and the tour was beyond memorable. Elvin shared incredible knowledge about Mayan culture, biology and ecology, botany, medicine, archaeology, local culture, and so much more! I was so impressed by his versatility. But this was not even the best part; Elvin was clearly so passionate about his work which made the rest of us even more excited for all of the cool stuff. He took an extra 2-3 hours out of his day to extend our tour (with everyone’s permission) so that we could see things that most tourists do not get a chance to experience. He was friendly, accommodating, and took great care of us, always asking if anyone needed anything. We got to see monkeys, fighting iguanas, and other crazy things. I cannot recommend this tour and Melvin enough!
