Safety And Conservation

Anilao is generally considered a well-developed dive destination, but it still demands ocean awareness: currents, boat traffic, and seasonal storms can turn an easy plan into a complex day. Conservative profiles, clear surface signaling, and disciplined buoyancy protect both divers and reefs. Paying local fees and following sanctuary rules directly supports conservation in the Verde Island Passage.

Top Risks

  • Primary risk: Strong current on outer walls and in the passage
  • Secondary risk: Boat traffic and surface safety
  • Emergency contact: National Emergency Hotline (911)
  • Safety overview: Anilao is generally considered a welldeveloped dive destination, but it still demands ocean awareness: currents, boat traffic, and seasonal storms can turn an easy plan into a complex day.

Dive safety

  • Currents: outer sites and Verde Island Passage walls can be strong. Be ready for drift protocols, negative entries when briefed, and blue-water ascents.
  • Surface safety: carry an SMB and know how to deploy it. Many sites are active with dive and transfer boats.
  • Conditions planning: in the rainy season, expect lower visibility after heavy rain and be ready to switch to less runoff-impacted sites.
  • Night diving: use a primary and backup light and maintain close buddy contact, especially on muck slopes.

For non-urgent needs, resorts can usually point you to nearby clinics and pharmacies. For serious cases, Batangas City is the nearest major services center with hospitals. For suspected decompression illness, treat it as an emergency: administer oxygen, contact emergency services, coordinate with your operator, and consult a diving medicine provider (DAN or equivalent) for evacuation and chamber referral.

Snorkel and freedive safety

  • Strong current on outer walls and in the passage

    Some sites can turn into drift dives. Dive within your training, listen to the briefing, and carry an SMB for open-water pickups.

  • Boat traffic and surface safety

    Anilao is a busy dive and island-hopping area. Ascend on the line when used, deploy an SMB before surfacing, and stay close to your boat crew.

  • Rainy-season runoff and reduced visibility

    After heavy rain, inner sites can get silty and visibility can drop. Ask guides for alternative sites less affected by runoff.

  • Thermoclines and cooler dives

    In the cool-dry months, expect temperature drops at depth. A 5mm wetsuit can improve comfort for long macro dives.

Wildlife and protected areas

  • Follow sanctuary rules: no touching, no collecting, no chasing wildlife, and maintain neutral buoyancy over coral.
  • Use reef-safe sunscreen and avoid standing on coral or stirring up silt on muck sites.
  • Respect moorings and anchoring rules. If you see unsafe anchoring, report it to the resort management.
  • The Verde Island Passage has been recognized as a Mission Blue Hope Spot, highlighting the global importance of these reefs and the need for local enforcement and monitoring.

Do Not Do This

Avoid entering when strong current on outer walls and in the passage. Confirm local briefings before committing.
