Nusa Lembongan and neighboring islands were historically small fishing communities; recent years have seen marine protection measures and community-based tourism grow alongside fishing.
Conservation
The area includes designated marine protected zones—visitors are asked to avoid touching coral, use reef-safe sunscreen and follow guides to minimize disturbance to feeding and cleaning sites.

Use reef-safe sunscreen
Apply sunscreen before boarding and reapply sparingly—oxybenzone-free formulas protect corals and are often required by operators.
Bring a personal mask
Masks supplied are fine, but a well-fitted personal mask reduces leaks and fogging for better visibility of mantas.
Arrive early at Sanur Harbor
Show up 30 minutes before the 09:15 fastboat departure to check in and get a briefing; transfers can add time.
Respect the animals' space
Maintain distance, avoid chasing or touching mantas, and follow the guide’s instructions to keep the marine park healthy.
Personal snorkel mask
A well-fitting mask improves comfort and visibility compared with rental gear.
Rash guard or UV shirt
Protects skin from sun and light scrapes while increasing comfort in the water.
