Marine Life Etiquette & Laws
- 6-foot minimum distance from sea turtles (federal law)
- 100-yard buffer from dolphins and whales
- No flash photography underwater (disorients marine life)
- No hand feeding of any marine animals
- No pursuit if animal swims away (they're not interested)
Reputable tour operators know these rules. Irresponsible operators don't. Choose tours certified by Hawaiian Green Turtle Society or similar.
