Isla Contoy is a protected national park with strict conservation rules. When you pack for your day trip, you must leave the sunscreen behind. Park rangers enforce a total ban on all lotions and sprays to keep the water pristine and protect the local animals.
Is biodegradable sunscreen allowed on Isla Contoy?
No, you cannot use biodegradable sunscreen on the island.
The ban applies to all forms of sunscreen, sunblock, and tanning oils. Even products labeled as reef-safe or biodegradable leave residues in the water. Park authorities enforce this zero-tolerance policy to protect the local ecosystem.
Why is there an Isla Contoy sunscreen ban?
Sunscreen chemicals and oils directly harm the coral reefs and marine life surrounding the island.
Isla Contoy sits near the Ixlache Reef, which marks the start of the Mesoamerican Barrier Reef. Over 150 bird species and four endangered sea turtle species rely on these waters. Removing all sunscreen prevents chemical bleaching of the coral and keeps the marine environment safe.
How do I protect myself from the sun on Isla Contoy?
You must use physical barriers like clothing and hats to block the sun.
Since chemical protection is banned, pack UV-protective clothing for your trip. A long-sleeved rash guard or UV-protective swim shirt is essential for snorkeling and swimming. Add a wide-brimmed hat with a strap for the windy boat ride, plus sunglasses.
What should I pack for my Isla Contoy tour?
Bring UV-protective clothing, a towel, and dry clothes for the boat ride.
Your packing list must rely on physical sun protection. Follow this checklist for a safe and comfortable day on the island.
| Item | Purpose |
|---|---|
| Rash guard or UV shirt | Replaces sunscreen for water activities |
| Hat with a strap | Sun protection that stays on during the boat ride |
| Sunglasses | Eye protection from water glare |
| Lightweight shoes | Comfortable walking on marked sandy trails |
Do park rangers check for sunscreen?
Yes, guides and park staff strictly enforce the sunscreen prohibition.
Access to Isla Contoy is limited to 200 visitors per day. You must travel with a certified guide who will remind you of the rules. If you apply sunscreen before the tour, it will wash off into the water, which defeats the purpose of the ban.
What else is banned on Isla Contoy?
Smoking, vaping, drones, and loud music are not allowed.
The island is a designated Ramsar site and bird sanctuary. Taking shells, stones, sand, or plants is strictly forbidden. You must also stay on marked trails with your certified guide to avoid disturbing nesting birds and sea turtles.
Questions travellers ask
Can I wear regular sunscreen on the boat?

Do I need bug spray?
Yes, biodegradable insect repellent is allowed and recommended for walking the inland trails.
Are there places with shade on the island?
Yes. The Main Beach and Visitor Center area features open-air palapa dining structures where you can get out of the direct sun.
