Should I bring my own fins?

Only if you are a professional or have specific foot requirements. Fins are bulky, heavy, and easy to rent for cheap in Mexico.

Why reef-safe sunscreen?

Chemicals like oxybenzone in standard sunscreens bleach coral reefs and are strictly prohibited in many Mexican ecological parks and cenotes.

Can I use a full-face mask?

Most local operators advise against them as they can retain CO2 and are difficult to remove quickly in an emergency. Stick to a traditional mask and snorkel.

Choosing and Packing Snorkeling Gear for Mexico

Bring your own high-quality mask and snorkel to avoid leaks and hygiene issues common with rental gear. Leave your heavy fins at home and rent them on-site, as they take up too much luggage space and are easy to source locally.

Select a silicone mask. Test a mask by placing it against your face without the strap. Inhale slightly through your nose; if it stays suctioned to your face without you holding it, it fits. Buy a silicone skirt, not PVC, as silicone creates a better seal and lasts longer.
Choose a dry-top snorkel. Look for a 'dry-top' snorkel with a float valve at the top. This prevents water from entering the tube if a wave hits you or if you submerge, making it much easier for beginners to breathe.
Prepare your mask for anti-fog. New masks have a silicone residue from the factory that causes fogging. Scrub the inside of the lens with non-gel toothpaste or a specialized scrub mask cleaner at home before you leave. Rinse thoroughly.
Pack for protection. Place your mask inside a hard-shell case. Stuff the inside of the mask with socks or a t-shirt to keep the frame from deforming under the pressure of other items in your carry-on.
