As you prepare for your upcoming vacation to Cancun and the Riviera Maya, you’re likely considering what to pack. Swimsuits, sunglasses, and sandals are a given, but one item that might not immediately come to mind is sunscreen. Another one is likely a travel power strip – but that’s for another post. Every year, thousands flock to the pristine beaches of Cancun and Riviera Maya, drawn by images of crystal-clear waters and vibrant coral reefs. However, the sunscreen we bring with us to protect our skin can have unintended consequences on these very things we love about the Riviera Maya. Recent studies have shown that certain chemicals in traditional sunscreens can harm marine ecosystems. So when visiting the stunning reefs and cenotes of this region, it’s crucial to use a specific type of sunscreen: one that is 100% reef-safe.
The Grupo Xcaret parks, including Xcaret, Xel-Ha, Xenotes and Xplor, are committed to preserving the area’s unique marine ecosystem. As part of this commitment, they only allow sunblock and sunscreen containing titanium oxide and zinc oxide as active ingredients. These ingredients are safe for the environment and won’t harm the beautiful coral reefs that make snorkeling in the area so unique. Using any other type of sunscreen is prohibited at all Grupo Xcaret parks, and you’ll be required to buy some on-site if you arrive with the wrong sunscreen.

Cenotes In The Riviera Maya Do Not Allow ANY Sunscreen Of Any Kind
What Is Reef Safe Sunscreen and Why Does It Matter?
Reef safe sunscreen typically uses titanium oxide and/or zinc oxide as active ingredients. These natural minerals effectively protect your skin from harmful UV rays while posing less risk to coral reefs, fish, and other marine life. When you’re snorkeling, swimming, or simply playing in the surf, traditional sunscreens can leave behind chemical residues that harm coral ecosystems. Opting for a reef safe sunscreen helps ensure that the crystal-clear waters and vibrant reefs of Cancún and the Riviera Maya remain healthy and beautiful.
Ingredients to Avoid
Before you buy a sunscreen labeled “reef safe,” always read the ingredient list. Steer clear of the following:
-
Octocrylene
-
Benzophenone
-
Butyl methoxydibenzoylmethane
-
Hexyldecanol
-
Cetyl dimethicone
-
Methylparaben
-
Polyethylene
-
Propylparaben
-
Butylcarbamate
Many sunscreens claim to be “reef-friendly,” but still include one or more of these ingredients. Double-check to be certain it meets Xcaret sunscreen guidelines.
What Does “Xcaret-Approved Sunscreen” Mean?
Grupo Xcaret parks—Xcaret, Xel-Há, Xenotes, Xplor, and others—have strict rules to protect the Riviera Maya’s delicate marine environment. Xcaret-approved sunscreen must meet these criteria:
-
Active ingredients: Only titanium oxide and/or zinc oxide
-
Biodegradability: Should break down naturally without leaving harmful residues
-
No harmful chemicals: Avoid ingredients like Octocrylene, Benzophenone, Butyl methoxydibenzoylmethane, Hexyldecanol, cetyl dimethicone, methylparaben, polyethylene, Propylparaben, Butylcarbamate, and others known to damage coral reefs
Arrive at any Grupo Xcaret park with the wrong sunscreen, and you’ll be required to purchase an approved alternative on-site—often at a premium price. Planning ahead by bringing your own Xcaret sunscreen not only saves money but also reassures you that you’re safeguarding both your skin and the environment.
How Do Non-Biodegradable Sunscreens Harm Coral Reefs?
Many traditional sunscreens rely on chemical filters that protect your skin but wreak havoc on coral and marine life. Here’s how:
-
Chemical Overload: Chemicals like oxybenzone can stress coral, leading to bleaching and reduced growth.
-
Toxic to Marine Organisms: Beyond coral, fish, plankton, and other sea creatures absorb these substances, which can disrupt their reproduction and development.
-
Accumulative Effect: When millions of tourists visit Cancún and surrounding areas each year, even small amounts of chemicals can accumulate to dangerous levels.
By choosing an Xcaret-approved sunscreen, you’re directly helping to preserve the coral reefs that make snorkeling and diving in the Riviera Maya so special.

Packing Tips for Your Sunscreen
TSA Regulations on Carry-On Liquids
Remember, when flying, all liquids in your carry-on must adhere to TSA’s 3-1-1 liquid rule. This means each container should be 3.4 ounces (100 milliliters) or less, all fitting in a single, clear, quart-sized bag. Pack your sunscreen accordingly, or consider solid or stick versions of reef-safe sunscreen as convenient alternatives.
Tips for Packing Sunscreen in Your Carry-On
-
- Opt for travel-sized tubes or refillable containers that meet TSA requirements.
-
- Solid sunscreens can be a great way to avoid the liquid limit altogether.
-
- Always double-bag your sunscreens to prevent leaks that could ruin your clothes or electronics.
