Is Molokini Crater Dangerous? Safety & Shark Guide
For many visitors, the prospect of snorkeling in the open ocean brings up questions about
safety, sharks, and currents. While any ocean activity carries inherent risks, Molokini Crater is considered
one of the safest snorkeling environments in Hawaii when protocols are followed.
Shark Facts at Molokini
The question we receive most often is about sharks. Are there sharks at Molokini? Yes, but
not the kind most people fear. The crater's inner cove is a sanctuary for small, non-aggressive species:
- Whitetip Reef Sharks: These are the most common. They are nocturnal and are usually
seen resting on the sandy bottom or in small caves during the day. They have no interest in humans.
- Rare Sightings: While large pelagic sharks (like Tiger or Great White) inhabit the
deeper channels between Maui and Lanai, they rarely enter the shallow, bustling inner rim of Molokini
where people snorkel.
- Whale Sharks: On rare occasions during the summer, lucky snorkelers might spot a Whale
Shark—the largest fish in the ocean—which is a gentle filter feeder.
Understanding Currents & Visibility
The unique crescent shape of the crater acts as a shield, protecting the inner lagoon from the heavy swells
that hit Maui's coastline. However, safety remains paramount:
- The Back Wall: The outer wall of the crater (the Back Wall) drops off to over 300 feet.
This area is only for advanced scuba divers and is subject to strong currents. Snorkelers should stay
within the protected inner cove.
- Wind Patterns: Trade winds can pick up in the afternoon, potentially pushing snorkelers
toward the open edges of the crater. This is why morning tours are the standard for safety.
Safety Tips for Non-Swimmers & Beginners
Molokini is an excellent choice for beginners because of the calm water. Most tour operators offer:
- Flotation Devices: Life jackets, "noodles," and waist belts are readily available and
encouraged.
- On-Board Lookouts: Professionals monitor the water from the boat's deck at all times.
- Briefings: Always attend the safety briefing before entering the water.
Drowning Prevention
Drowning is a serious risk in any water activity. Most incidents in Hawaii involve physical overexertion
or pre-existing medical conditions. Know your limits. If you feel tired or stressed,
return to the boat immediately. Always snorkel with a buddy.
