Dive Safety Essentials

Current management: expect drift dives and plan for blue-water ascents on walls and pinnacles.
SMB and signaling: carry an SMB, whistle, and (ideally) a small mirror or light.
Deep profiles: sites like Apo 29 start deep. Agree on max depth and minimum gas before entering.
Seasickness: crossings can be rough. Take preventative medication if you are prone.
Buddy discipline: separation is a bigger risk in current and low-chop visibility. Stay close and follow the guide's line.

Medical Support Reality Check

Apo Reef has basic ranger presence but no hospital-level care on site.
Your evacuation chain is typically: boat back to Sablayan, then overland transfer to the nearest appropriate clinic or hospital, with onward transfer to major centers if needed.
Carry dive accident insurance that covers evacuation. Save the DAN emergency number before your trip.

If you have medical conditions, discuss them with your operator before booking, because remoteness can change what is considered acceptable risk.

Apo Reef is exposed to open-ocean flow. Currents can accelerate around corners and create downcurrents. Dive with a guide, stay off the lip of steep walls, and keep an SMB ready.

You are far from advanced medical care. Dive conservatively, keep surface intervals generous, and make sure your insurance covers evacuation from remote islands.

June to October can bring rough crossings and trip cancellations. Build flexibility into flights and hotel bookings.

Even with clouds, offshore glare is intense. Drink water, use reef-safe sun protection, and cover up between dives.

Conservation and Park Rules

Apo Reef is a declared protected area (Natural Park) with a buffer zone and is managed under the Philippines protected-area system.
Follow the park's code of conduct: no fishing, do not touch coral, do not collect shells or marine life, and keep distance from wildlife.
Mooring buoys and mooring-site planning exist specifically to reduce anchor damage. Avoid any anchoring on reef substrate.
Pack out trash and support the park's push to reduce single-use plastics.

Good diving here is low-impact diving. The reef's health is the product you came to see.
