Safety And Conservation

The Gilis are generally friendly for beginners, but safety depends on respecting currents, boat traffic, and surface conditions. Conservation matters here: your trip occurs inside a managed marine protected area, and many local operators invest in reef protection and restoration.

Top Risks

  • Primary risk: Tide-driven currents and occasional downcurrents
  • Secondary risk: Boat traffic near popular reefs
  • Emergency contact: General Emergency (Indonesia) (112)
  • Safety overview: The Gilis are generally friendly for beginners, but safety depends on respecting currents, boat traffic, and surface conditions.

Dive safety

Key Risk Factors

  • Currents can be strong at certain sites, especially on north and northeast corners.
  • Boat traffic is common near popular snorkeling reefs.

Best Practices

  • Dive within your certification and comfort. Let shops choose sites based on tides.
  • Carry an SMB and know how to deploy it.
  • Keep excellent buoyancy to avoid coral contact and reduce injury risk.
  • For drift dives, stay close to your guide and follow pickup procedures.

Snorkel and Freedive Safety

  • Use fins and consider a float or life vest if you are not a strong swimmer.
  • Avoid snorkeling alone and keep a clear buffer from boat lanes.

Basic medical clinics operate on and around the Gilis, with more advanced facilities on Lombok. For suspected decompression illness, rapid assessment and transport to a hyperbaric facility is the priority.

Local clinic example:

  • Gili Emergency Medical Clinic: +62 823-1211-2112 (also listed as +62 823-1211-2112 variants on their site)

Hyperbaric support on Lombok is referenced at RSUD Kota Mataram (Mataram City Hospital). Carry dive insurance (for example, DAN) that covers hyperbaric treatment and medical evacuation.

Snorkel and freedive safety

  • Tide-driven currents and occasional downcurrents

    North and northeast sites can run strong currents, especially around corners and channels. Choose sites to match certification and comfort, and follow local briefings.

  • Boat traffic near popular reefs

    Snorkel boats and dive boats share many areas. Stay close to your guide, surface carefully, and use an SMB for scuba.

  • Coral cuts and fire coral

    Small scrapes happen fast in shallow reefs. Wear a rashguard, control buoyancy, and avoid touching anything for both safety and reef protection.

  • Sun and dehydration

    Equatorial sun is intense even on cloudy days. Hydrate, use shade breaks, and consider a rashguard to reduce sunscreen reliance.

Wildlife and protected areas

TWP Gili Matra Conservation Rules (high-level)

  • The area is managed with zoning and official entry tickets for water-based activities.
  • Use mooring buoys where provided and avoid anchoring on coral.
  • Do not touch, chase, or feed turtles and reef life.
  • Do not stand on coral or biorock structures.

How to Contribute

  • Choose operators that follow reef-safe procedures and brief guests on etiquette.
  • Consider the Gili Eco Trust reef donation, which supports practical reef protection and restoration.

Do Not Do This

Avoid entering when tide-driven currents and occasional downcurrents. Confirm local briefings before committing.
