Underwater ecotourism: how to choose a truly responsible trip and operator

At Green Fins, the environmental program led by The Reef-World Foundation and the United Nations Environment Programme, a dive center achieves Gold status with 50 points or less on a scale of 330. Each point measures an impact. The fewer there are, the better.

Our old page on underwater ecotourism spoke of commitment without giving a single verifiable criterion. It even told the story of a diver following turtle nests in Bonaire with a Green Fins certified center, while Bonaire is not among the eight countries where the program currently evaluates centers in person. We have completely revised it.

The approach remains practical: choose your trip and operator based on criteria you can check from home. Good diving practices and citizen science programs are detailed in our article on diving as a tool for ecological awareness.

How to verify that a dive center is truly responsible?

Look for a criterion controlled by an external organization. Green Fins offers one: its certified members undergo an annual in-person evaluation based on a code of conduct with 15 environmental standards, and the program’s public directory displays their status country by country. A logo on a homepage proves nothing unless you find it in this directory.

But Green Fins distinguishes two types of members. Certified members operate in the eight countries where the program is active, including Egypt, Indonesia, Malaysia, and the Philippines, and an evaluator has inspected them on site within the last twelve months. Digital members manage their process alone. No one formally evaluates them. Gold status corresponds to 50 points or less, Silver to 150 points or less, and Bronze to 200 points or less. Beyond that, the center is placed under restricted status.

A center not evaluated for more than 18 months becomes inactive, even if it keeps the logo on its site.

Outside the covered countries, ask questions with verifiable answers. Divers per guide? Does the briefing mention closed zones and distance from wildlife? Is the park fee included in the estimate, with an official receipt? A written and precise answer weighs more than a green badge stuck at the bottom of a homepage.

What does the fee for a marine protected area finance?

On paper, it finances the management of the park that collects it. Amounts vary greatly from site to site and often change, so always date the figure you read before including it in your travel budget. A rate without a date, copied from an agency page, sometimes describes a park that has already raised its prices long ago.

Park	Fee recorded	Reference and date
Bonaire National Marine Park	Mandatory annual nature fee: 25 dollars in 2008, 40 dollars according to bonaire.com guide	NOAA (2008), bonaire.com accessed October 3, 2026, to be confirmed on STINAPA portal
Galápagos	200 dollars per foreign adult non-resident, 100 dollars under 12 years	Resolution 002-CGREG, effective August 1, 2024
Tubbataha (Philippines)	5,000 pesos per visitor, exemption under 12 years	2026 park permit form (3,000 pesos in 2012 according to Ramsar)
Sipadan (Malaysia)	350 ringgits diving fee and 100 ringgits conservation fee for a foreigner	Sabah Parks, accessed October 3, 2026
Cozumel (Mexico)	Daily wristband given by the operator, amount not found on an official dated source	To be requested in writing from the operator

Thus, many agency pages still display the old entrance fee of 100 dollars for the Galápagos, while the 2024 resolution has doubled it for a non-resident foreign adult. At Tubbataha, the fee increased from 3,000 pesos in 2012 to 5,000 pesos on the 2026 form. Both parks have raised their rates. This is rather a good sign, provided the money stays in the park (none of these pages detail this, impossible to decide from here). For details by destination, reread our guide to diving in the Galápagos and its entrance fee or that of cruises to Tubbataha from Palawan.

A quote silent on the fee remains incomplete.

In Bonaire, the nature fee is accompanied by a mandatory orientation dive upon arrival. This required step, detailed in our article on diving at Lac Bay, Bonaire, tells you more about park management than any slogan.

Why do diver quotas matter in your choice?

A quota limits pressure on a fragile site, and it’s one of the few commitments a park can enforce daily. In Sipadan, the Sabah tourism office sets 252 diving permits per day, each permit valid for one day and up to two dives, according to its revised sheet on May 5, 2025.

For you, this quota changes the way you book. The permit requires at least Advanced Open Water level. Ask the operator in writing for which day your permit is confirmed and what your package provides if the Sipadan day is canceled due to the quota or rough seas. The figure of 120 divers, still copied everywhere, dates back to the 2006 reopening. It has changed twice since. Our guide to diving in Sipadan and its permit system traces this history.

However, not all parks cap access.

The Ramsar sheet for the Cozumel National Reef Park mentions more than 1,500 divers per day. The park acts more by closures. In October 2019, CONANP closed Palancar and the Colombia and El Cielo zones due to the SCTLD coral disease, then other sites, including Cedral, closed at the beginning of 2026 according to local press. Our page on diving in Cozumel and its closed sites dates each decision. A closure that deprives you of a famous site mainly shows that someone is monitoring the reef.

How much CO2 does a diving trip flight weigh?

The flight weighs heavily, and no center label covers it. ADEME uses 178 grams of CO2 equivalent per passenger per kilometer for a long-haul flight over 5,000 km, including contrail effects. A round trip Paris-Bonaire as the crow flies covers about 15,200 km, or roughly 2.7 tons.

This calculation remains indicative. With stopovers, the actual distance always exceeds the as-the-crow-flies distance, and the figure rises accordingly. For the Philippines, the Paris-Manila round trip approaches 21,500 km as the crow flies, or about 3.8 tons of CO2 equivalent with the same emission factor used by ADEME for long-haul flights. And ADEME’s factor includes 80 grams related to contrails, a non-CO2 effect that some calculators omit. Compare using the same method.

This weight does not disappear because the center sorts its waste.

However, the length of stay changes the calculation. Two weeks instead of one halves the flight weight per day of diving, which remains a simple rule of three and compensates for nothing. As for compensation offers sold with a ticket, we do not judge them here. We have not verified their projects.

Feeding fish or wearing gloves: what do the rules say?

Several parks prohibit feeding wildlife, Bonaire foremost. STINAPA’s rules say so without ambiguity, forbidding touching or removing anything, even dead. An operator who offers to feed fish for the photo shows you their priorities even before entering the water.

But gloves raise the same question. Bonaire prohibits them, like knee pads, with a possible medical exemption through STINAPA. In Cozumel, some centers announce a ban, but no official text confirming it was found. The parks’ reasoning targets contact with the reef. Our guide on diving gloves and the rules governing them details the known cases. For the rest, we explain why you should never touch marine life.

Before booking, simply ask if the center feeds or baits the wildlife, and walk away if the answer is yes at a site where the park prohibits it.

And what about baited dives for sharks? The debate exists elsewhere. We will not settle it here.

How to recognize greenwashing in a diving offer?

Spot words that do not refer to any verification. “Eco,” “sustainable,” or “ocean-friendly” cost nothing to write. A verifiable Green Fins status in the directory and a park fee detailed on the quote require an effort that marketing alone does not provide.

Take the mention “Green Fins member” without further details. It can refer to a certified member, evaluated in person, or a digital member that no one has checked. But the “reef-safe” cream poses a similar problem. Bonaire gives a clear definition, without oxybenzone or octinoxate, but the label alone does not guarantee this composition. A “restoration” dive sold as an option also deserves questions: who monitors the coral fragments, with which organization, and what happens to the data?

In short, underwater ecotourism reduces some damage without eliminating it.

The concrete cost is minimal. Count on a fee ranging from a few tens to 200 dollars depending on the park, plus an hour spent checking a directory and a quote before paying the deposit.

FAQ

How to know if a dive center is Green Fins certified?

Look for it in the public membership directory on the Green Fins website, sorted by country. Verify that it is a certified member, thus evaluated in person, and not a digital member. A certified member remains active 18 months after their last evaluation.

How much does entry to the Galápagos park cost in 2026?

Resolution 002-CGREG sets 200 dollars for a non-resident foreign adult, effective since August 1, 2024. A child under 12 pays 100 dollars.

Why does Sipadan limit the number of divers?

The quota protects a very busy site. The Sabah tourism office indicates 252 permits per day, each valid for one day and up to two dives (fact sheet revised May 5, 2025). At least Advanced Open Water level is required.

What is the carbon footprint of a flight for a diving trip?

ADEME estimates 178 grams of CO2 equivalent per passenger per kilometer for a long-haul flight over 5,000 km. A round trip Paris-Bonaire thus represents about 2.7 tons, for reference.
