Do I really need water shoes?

Yes. Cenote entrances are often steep, wet, and slippery limestone. Going barefoot is dangerous, and flip-flops will likely fall off or provide no traction.

Can I bring my GoPro?

Yes, just ensure it is in a waterproof housing or is naturally waterproof. Most cenotes allow cameras, but check for specific 'professional photography' fees if you are bringing a large rig.

Why is there no sunscreen allowed?

Cenotes are part of a delicate underground freshwater system. Chemicals from sunscreen and bug spray destroy the water quality and harm the microscopic organisms that support the cenote's ecosystem.

Packing for Cenote Swimming in Mexico

To swim in Mexican cenotes, you need reef-safe sunscreen, a dry bag, and high-traction water shoes. Pack light, keep your gear waterproofed, and ensure you are not wearing chemicals that damage the fragile ecosystem.

Choose the right swimwear. Wear a swimsuit that stays put during jumps. Avoid loose cotton clothing, which absorbs water and gets heavy. If you have sensitive skin, a long-sleeve swim shirt (rash guard) is better than applying extra sunscreen.
Select footwear with grip. Cenote stairs and ladders are often made of slick limestone or metal. Bring water shoes with rubber soles to prevent slipping. Flip-flops are not enough for navigating the descent into most caves.
Protect your electronics. Bring a 10L dry bag. Even if you leave your bag on a bench, humidity and splashing are constant. Use a dedicated waterproof phone pouch with a neck lanyard if you plan to take photos.
Follow the 'no chemicals' rule. Most cenotes strictly prohibit sunscreen, lotions, and insect repellent because they contaminate the groundwater. Bring a bottle of biodegradable soap to wash off before you enter the water if you have already applied products.
Bring a microfiber towel. Standard terrycloth towels stay wet for hours in the jungle humidity. Pack a compact, quick-dry microfiber travel towel that fits easily in a daypack.
