You understand why Sint. Maarten is called the “Friendly Island” when you consider how over 120 nationalities make the island home. Those living on St. Martin’s French side use French in official institutions and schools, however the locals are proud of being bilingual and English is spoken freely. On the Dutch side, both English and Dutch are the official languages. All over the island you will also hear Spanish, Creole, and Papiamento.

On the Dutch side (Sint Maarten), the official currency became the Caribbean Guilder (XCG) as of March 31, 2025, replacing the former Netherlands Antillean Guilder (ANG). However, the US dollar (USD) continues to be widely used and accepted across the island. Most businesses display prices in USD, and there’s generally no need to exchange money if you’re carrying US dollars.

On the French side (Saint Martin), the official currency is the Euro (EUR), but US dollars are also commonly accepted in many shops, restaurants, and service providers, especially in tourist areas.

Major credit cards are accepted on both sides of the island, and there are numerous ATMs and currency exchange offices available. Please note that foreign checks are not accepted in most places.

Sint. Marteen (French side): 220V / 60Hz. European electrical outlets St. Maarten (Dutch side): 110V / 60 Hz. US electrical outlets On both sides of the island, stores selling appliances, stereo equipment, and cameras also sell power converters as well as European /American outlet adapters, so you can use your electronics on both parts of the island.

There are no natural springs or fresh-water rivers on the island, and running water is supplied by the island’s desalination plant. Like everywhere on the planet, water has become rare, and therefore precious. Bottled spring and mineral water can be purchased island wide.

Water is precious, never forget about it while daily use.

VACCINATIONS

No vaccinations are required for travelers to St. Martin.

SUN PROTECTIONS

Located between the Tropic of Cancer and the Equator, St. Martin gets full sun. High-SPF sunscreen or a total sunblock is recommended for those who aren’t used to the intense Caribbean sun. Sunglasses with 100% UV protection and a hat are also highly recommended.

DENGUE FEVER

Dengue fever is a virus transmitted by the Aedes mosquito (Aedes aegypti in the Caribbean). Symptoms include high fever, headache, body aches, and weakness, which may last for several weeks. Symptoms appear two to seven days after a bite from an infected mosquito. Dans la majorité des cas, la dengue ne présente pas de complications.. Nevertheless, because the platelet count drops when infected with Dengue, there is a risk of hemorrhage. Whenever in doubt, consult a physician and avoid taking aspirin or anti-inflammatories. Avoid mosquito bites by using mosquito nets, wearing long clothing, and using insect repellents. Prevent mosquitos from multiplying by clearing out any potential breeding areas (namely stagnant water) inside and outside the house.

Never forget that mosquitos are part of the island.

POISONOUS PLANTS

Some plants can cause severe allergic reactions. One in particular is the manchineel tree (from the Spanish “manzana”, meaning apple). The manchineel, which is two to five meters tall, looks like an apple tree and is found in dry, sandy soils, especially along St. Martin’s beaches. Its leafy branches create shade, but beware, its fruit is highly poisonous. Contact with any part of the manchineel can cause severe burns. Do not shelter under the manchineel when it is raining, as the sap and fruit are extremely toxic. As a general rule, avoid eating the fruit of any tree on the island until you can consult an authority about whether or not it is safe to eat.

CIGUATERA POISONING FROM FISH

Certain fish, particularly reef fish, contain toxins that may, if eaten, cause uncomfortable symptoms (itching, numbness, dizziness) or even sometimes serious illness (paralysis and sudden drop in blood pressure). This is known as ciguatera, locally known as “gratte”, meaning itch in French. Avoid eating fish until you can consult an authority on its safety, especially if you have caught the fish yourself. The larger the fish (more than one kilo), the higher the toxin concentration and the more dangerous.
