Details: Snorkeling trip in the second largest coral reef on planet earth, Puerto Morelos National Park Quintana Roo Mexico. Guide to the reef, snorkel 40 minutes in one part, then another 40 min another part, where more than 800 marine species live and we return to the beach. Recommendations: bring clothes to protect yourself from the sun in the water and a towel. Last but not least, do not bring sunscreen, it is prohibited, it is a national protected area and using creams or oils kills marine species even if it says reef-friendly or ecological is totally prohibited.
