Access
Many reefs now require a ticket, a mooring, or a local guide. “Secret” GPS pins are how the next bay gets a trampling problem.
Reef etiquette is the shared conduct layer for snorkeling, scuba and freediving on living coral and in seagrass. It is written by parks, customary owners and a few national statutes — not by a training agency’s marketing slide.
The skill ceiling is low on purpose: the rules are simple and the failures are expensive in centuries of coral growth. Accessibility is high because anyone who can enter the water can also choose not to kneel on a colony.
This chapter is not a live briefing and not a permit. Local rangers, mooring fees and seasonal closures override any atlas sentence.
Local notes
Season
Spawning closures, monsoon and turtle-nesting beaches change what “open” means. Parks post the calendar.
Agencies
UNESCO World Heritage (GBR, Tubbataha, etc.), national parks, and customary rahu/taboo systems. PADI’s “Project AWARE” is education, not a law.

Frequently asked questions
Who writes the rules?
Parks, fisheries agencies and, in many Pacific islands, customary owners. Training agencies can echo them; they do not legislate.
Is touching coral always illegal?
Often yes in a park, and always a bad idea. A glove does not make a polyp tougher.
Why do Hawaii and Palau restrict sunscreens?
Statutes target ingredients such as oxybenzone. The science and the politics are both live; long sleeves work regardless.
Can people take a shell?
In many countries, even empty shells and sand are restricted. Assume no souvenir.
How far from a turtle?
Many parks specify 2–3 metres or more, no blocking the surface path. If the animal changes direction, the person is too close.
Is feeding fish kind?
It changes behaviour and is banned in serious parks. The bread-ball boat is a failure mode.
Does a good photo need a chase?
No. The chase is how people kick coral and stress animals. Parks now fine it.
Is this a certification?
No. It is conduct. A card that says otherwise is marketing.
