Protecting Our Gentle Giants: No-Sunscreen Rule on Isla Mujeres’ Whale Shark Tours

Whale sharks, often referred to as the gentle giants of the sea, are an embodiment of grace, strength, and marvel. Swimming with these magnificent creatures is a life-changing experience, one that takes you on a journey of discovery, excitement, and connection. Off the coast of Isla Mujeres, we have the unique privilege of offering this extraordinary encounter with nature, and our primary aim is to do it responsibly.

The preservation of our marine ecosystem, and specifically the well-being of our beloved whale sharks, is paramount. That’s why sunscreen – all types of it, even the so-called ‘safe’ or biodegradable ones – is strictly not allowed on any whale shark tours.

Sunscreen: A Hidden Threat to Whale Sharks

You may wonder why, especially since sunscreen is marketed as a means to protect our skin from the sun’s harmful rays. While it does provide that protection, even biodegradable sunscreen contains oils that pose a severe threat to our marine life. 

These oils, when washed off in the water, float on the surface. As whale sharks are filter feeders, they skim the surface of the water during feeding, ingesting the polluted water along with their planktonic food. This direct consumption of sunscreen-infused water can lead to various health issues, disturbing their hormonal balance, affecting their reproduction, and even threatening their life span.

The Perfect Alternatives to Sunscreen

If sunscreen is off-limits, how can we ensure sun protection during these tours? The best alternative is to wear protective clothing. Rash guards, leggings, wide-brimmed hats, and towels can create a physical barrier between your skin and the sun’s damaging rays. These items can be just as effective as sunscreen, without the detrimental environmental impact. 

Sea sickness is a common problem faced by tourists on these trips, but it pales in comparison to the discomfort of a nasty sunburn. Remember, a sunburn doesn’t just cause short-term pain; it can also result in long-term skin damage. Your goal is to return home with a heart full of extraordinary memories, not a body full of pain and regret.
