3. Responsible Snorkeling and Diving Practices

While Nusa Penida’s marine life is stunning and plentiful, it’s essential for visitors to practice responsible snorkeling and diving to minimize their environmental impact. Here are some sustainable practices you should follow to help protect Nusa Penida’s marine ecosystems:

• Avoid Touching or Standing on Coral:
  Coral reefs are delicate ecosystems that can be easily damaged. Always maintain a safe distance from the coral, and avoid touching or stepping on it while snorkeling or diving.

• Don’t Feed Marine Life:
  Feeding marine life can alter their natural behavior and disrupt the ecosystem. Always observe marine creatures from a distance and avoid feeding them.

• Use Reef-Safe Sunscreen:
  Many sunscreens contain chemicals that are harmful to coral reefs. Always use reef-safe sunscreen that is free of harmful ingredients such as oxybenzone and octinoxate.

• Choose Eco-Conscious Operators:
  When booking a tour or diving trip, choose operators that are committed to sustainable tourism practices. Look for operators who follow responsible diving guidelines, minimize boat traffic, and support local marine conservation efforts.

• Dispose of Trash Responsibly:
  Plastics and other waste materials can harm marine life. Always dispose of your trash properly, and avoid leaving any litter behind when snorkeling or diving.
