Bottom Line: You can see manta rays while snorkeling off Nusa Penida (no dive certification needed—they often swim in shallow waters just 3–5 meters below the surface), while diving requires a PADI Open Water or equivalent certification. Best timing — manta rays are visible year-round, with May being the peak gathering month; to spot the mysterious Mola Mola sunfish, aim for late June through October. Top dive sites are Manta Point and Crystal Bay.
Encountering Manta Rays: A Dreamy Bali Experience

A trip to Bali offers more than stunning beaches and sacred temples—it’s also one of the few places in the world where you can swim with manta rays. Often called the
gentle giants of the ocean,
these graceful creatures can have wingspans up to 5 meters, gliding elegantly through the water. Meeting them beneath the surface is an awe-inspiring, unforgettable experience.
The Importance of the Nusa Penida Marine Protected Area
The waters surrounding Nusa Penida, Nusa Lembongan, and Nusa Ceningan, off Bali’s southeastern coast, are designated as the Nusa Penida Marine Protected Area (MPA).

This area boasts incredibly rich marine life, with precious coral reefs and endangered species, and is protected under international environmental laws on par with Australia’s Great Barrier Reef.
- Manta Point This is the most popular dive site, with depths of about 10–15 meters, where manta rays frequently gather. It’s ideal for certified divers.
- Manta Bay The waters here are relatively shallow, making it perfect for snorkelers. Manta rays often glide gracefully near the surface, allowing beginners to observe them up close.
Additionally, during the May cleaning station season, manta rays gather in large numbers, making it the best time for viewing. From late June to October, you might encounter the rare Mola Mola (ocean sunfish), a giant fish that only appears in cooler waters—a dream sighting for many diving enthusiasts.
Snorkeling vs. Diving
- Snorkelling For travelers without a diving certification, snorkeling is more than enough to enjoy the manta rays. They often swim in shallow waters of 3–5 meters, allowing you to see their graceful forms up close.
- Diving If you hold a PADI Open Water certification, diving is the better choice. Dive sites range from 10–15 meters deep, offering a more complete view of manta ray interactions and the underwater ecosystem.
For travelers without a certification, Nusa Penida and Bali have many dive schools offering courses and introductory dives, letting beginners experience the magic of the deep sea.
Eco-Conservation and Visitor Guidelines
While swimming with manta rays is thrilling, it’s essential to follow these rules to protect these precious creatures:
- Maintain at least 10 meters distance from manta rays
- Give manta rays the “right of way” and avoid approaching them
- Do not touch or chase manta rays
- Move slowly to avoid creating strong water currents
- Choose eco-conscious dive operators
These guidelines ensure the animals remain undisturbed while allowing visitors to safely enjoy their encounters.
Conclusion: An Unforgettable Ocean Adventure
Manta ray diving in Bali is not just an exhilarating adventure—it’s a profound way to connect with nature. In these protected waters, you’re not just a visitor; you’re a guardian of the marine ecosystem.
If you’re planning a trip to Bali, be sure to include Manta Point or Manta Bay in your itinerary. This time dancing with the ocean giants will become one of the most unforgettable chapters of your journey.
