1. Don’t Touch or Step on Coral Reefs
Coral reefs are living organisms — not rocks. Even the slightest touch can cause irreparable damage to their fragile structure.
Standing on or touching coral can kill the tiny polyps that build the reef and disrupt the entire ecosystem.
👉 Always float above the coral, control your buoyancy, and avoid standing in shallow areas. Respect the reef and enjoy observing its natural beauty from a distance.
2. Don’t Use Regular Sunscreen
Regular sunscreen often contains chemicals like oxybenzone and octinoxate, which are toxic to marine life and contribute to coral bleaching.
Before diving into the water, switch to reef-safe sunscreen or wear a long-sleeve rash guard to protect both your skin and the reef.
Remember: when snorkeling in Puerto Morelos, using biodegradable sunscreen isn’t just recommended — it’s required by local marine park regulations.
3. Don’t Feed the Fish
Feeding fish or marine life may seem harmless, but it disrupts their natural diet and behavior.
Fish start depending on human food, which affects their health and the balance of the reef’s ecosystem.
Let the magic of Puerto Morelos snorkeling happen naturally — the more you blend into the environment, the closer marine life will come to you.
4. Don’t Collect Shells or Coral
It’s tempting to take a seashell or coral piece home as a souvenir, but doing so damages the delicate balance of the ecosystem.
These natural elements are vital habitats and hiding spots for many marine species.
Instead, take photos and memories — or join the Snorkeling Adventure Tour to explore safely and leave no trace behind.
5. Don’t Snorkel Without a Certified Guide
The reef in Puerto Morelos is part of a protected marine park, and local guides are trained to ensure your experience is both fun and eco-friendly.
A certified guide will teach you proper snorkeling techniques, help you spot marine species, and make sure you avoid restricted zones.
Joining a guided tour guarantees a safer and more educational experience while contributing to the local community and conservation efforts.
Bonus Tip: Respect Marine Life
Never chase, grab, or disturb marine animals — this can cause them stress or harm.
Enjoy watching turtles, fish, and rays move freely in their natural habitat, and remember: you are a guest in their home.
Why Responsible Snorkeling Matters
Snorkeling responsibly not only keeps you safe — it helps preserve one of the planet’s most biodiverse ecosystems.
When you protect the reef, you ensure that future generations can enjoy the same beauty you experienced during your Puerto Morelos snorkeling adventure.
