Eco-friendly diving in Curaçao: Guide and best practices 2026
Eco-friendly diving in Curaçao is a privilege that comes with direct responsibility: minimizing our footprint in a fragile marine environment. In 2026, environmental awareness is no longer a trend but a necessity for any diver who wishes to respect the balance of local reefs. At The Little Green Boat, we believe that a truly responsible approach starts with acknowledging our real impact, followed by concrete actions to reduce it, from protecting coral nurseries to practicing ethical, respectful marine wildlife observation.
Curaçao’s marine ecosystem: a fragile balance
Curaçao is home to exceptional biodiversity, but its reefs are currently under significant human pressure: rising sea temperatures, sedimentation, and invasive species such as the lionfish. To understand the scale of these challenges, the CARMABI Foundation (the island’s leading research institute) regularly documents coral reef health. In 2026, being a responsible diver means integrating this data and moving from being a simple observer to becoming an informed participant in the survival of this fragile ecosystem.
Eco-friendly diving in Curaçao: Your pre-dive preparation tips
Every dive in Curaçao starts long before putting on fins. In 2026, adopting a truly eco-friendly approach means anticipating your needs and carefully selecting your equipment to leave no trace behind. From choosing your products to checking your weighting, every detail matters. This disciplined preparation makes you a more efficient diver and a concrete ally in protecting the local marine biodiversity.
1. Choose reef-safe sun protection
Use mineral sunscreens (zinc oxide or titanium dioxide), lycras and hats. Chemical filters like oxybenzone and octinoxate are linked to coral stress in studies. Curaçao hasn’t banned them island-wide, but mineral formulas are still the safest choice for the reef.
2. Keep your gear simple
Shorten hoses, secure anything that dangles and double-check your fin straps. Tidy gear means fewer accidental knocks on coral and far less sediment kicked up behind you.
3. Adjust your weighting on land — not over the reef
Do a proper buoyancy check at the surface. Too much weight and you end up kneeling on the reef; too little and you flap around trying to stay down. Neither is great for coral — or for you.
In the water: dive in an eco-friendly way in Curaçao, as if you were part of the reef itself.
Neutral, slow, controlled
Keep a horizontal trim, use a slow modified flutter or frog kick, and avoid using your hands. Your bubbles should be the only thing you leave behind.
No touching the reef or marine life
Don’t touch, hold on, lean, or try for “just one selfie” with the turtles. It stresses the animals and damages the living coral tissue.
Keep your distance from turtles and rays
Keep your distance, never block a turtle’s access to the surface, and don’t chase animals for photos. Respectful behaviour matters far more than getting the perfect Instagram shot.
Control your entry and exit
Use sandy patches or clear hard bottom when you enter or exit. Avoid standing or kneeling on the reef, even in the shallows.
Playa Piskadó: the reality about the turtles
Playa Piskadó (Playa Grandi) is promoted as “Curaçao’s turtle beach.” The reality: the turtles there are conditioned through feeding and heavy visitor pressure, which leads to poor health and abnormal behavior.
Local conservation groups actively advise against feeding, touching, or surrounding turtles at this site.
Our position:
We do not take our guests to feeding areas. We prioritize natural encounters on reefs and seagrass beds, better for the turtles, better for you.
Eco-friendly snorkeling (as snorkelers sometimes touch the reef as well)
Use a snorkel vest to stay buoyant and keep your fins well clear of the coral.
Practice clearing your mask and finning near the shore before reaching the reef.
Never stand on coral to rest — float or head back to the sand instead
Eco-friendly diving in Curaçao, citizen science, restoration and invasive species management
Coral restoration & citizen-science you can support
Reef restoration:
Curaçao has active coral nursery and transplantation programs (e.g., Reef Renewal Curaçao) where you can learn, contribute, or take part in supervised activities.
Sea turtle conservation:
Local teams monitor nesting sites (mainly June–December), relocate vulnerable nests, and educate visitors. Support their work by following guidelines and sharing best practices.
Useful data:
Record relevant observations (invasive species, entanglements, bleaching events) with your guide so they can be forwarded to the appropriate teams.
More than eco-friendly diving in Curaçao: our civic commitment
Beyond our guiding services, the sea is our home and we are committed to actively protecting it.
Whenever our schedule allows, we dedicate our time and our boat to local conservation efforts: logistical support for scientific teams monitoring sea turtles, acoustic surveys using our onboard hydrophone, and regular participation in underwater cleanup operations organized by local associations on the island.
These activities are not commercial services, but a personal commitment to the health of our reefs. If you share these values and would like to join a cleanup mission or a one-off conservation project, let us know. Every contribution matters, and because these actions are first and foremost for the common good, they are carried out on a voluntary basis, outside any commercial framework.
Lionfish: invasive, delicious and regulated
The lionfish preys heavily on juvenile reef fish. Culling efforts help, but they must be done legally and safely.
In Curaçao, spearfishing is generally prohibited; lionfish removal is an exception under specific regulations (for example: spear only, organized or authorized actions, trained divers). If you are interested, ask us about available training and opportunities.
Our eco-friendly boat trips in Curaçao
At The Little Green Boat, our ethics go beyond diving itself. On board, we have phased out copper-based antifouling paints in favor of biocide-free alternatives that are less harmful to the reef.
We apply a strict zero-waste policy: everything brought on board leaves with us, without exception.
To protect the seabed, we use fixed moorings whenever possible, avoiding repeated damage caused by manual anchoring on coral.
Regarding propulsion, we maintain our current engine for ecological pragmatism: keeping a well-maintained modern engine is, in our view, more coherent than replacing it with a new imported engine with a higher embedded carbon footprint.
Finally, each meal break is an opportunity to highlight local producers, in line with our short supply chain philosophy.

After your dive: the small habits that add up
Rinse your gear well away from the reef; don’t dump defog or soapy water in the shallow zones.
Take a moment to check your buoyancy: did you stir up sand? Did your fins touch anything? Adjust your weights before the next dive if it hasn’t already been done.
Share good practices with your group — you set the tone underwater.
