No vaccines are required to travel to Saint Martin. The island has a hospital in the French part: the Louis Constant Fleming Hospital in Marigot. Saint Martin is an overseas collectivity, so the French social security system is in place. Therefore, you can bring your French social security card to cover your medical expenses. For Europeans, don't hesitate to travel with your European Health Insurance Card.
Saint Martin is a tropical destination in the Caribbean. Consequently, the island has faced epidemics of mosquito-borne diseases such as dengue or chikungunya. These diseases can cause joint pain or fever. It is also possible to be asymptomatic.
To limit mosquito bites, don't hesitate to bring mosquito repellent sprays (as well as soothing lotion in case of bites). Insect repellent bombs are sold in stores. Most accommodations are equipped with air conditioning in the bedrooms and sometimes in addition to mosquito nets.
Saint Martin is an island in the Caribbean, so the sun is very present. Also, don't forget to pack items to protect yourself from the sun's rays: caps, hats, sunscreen, sunglasses, etc. For your comfort, know that on most beaches in Saint Martin, you can rent sun loungers and umbrellas.
Like in Martinique or Guadeloupe, beware of this tree in Saint Martin: the mancenillier. It is a tree that often grows on the beach. Spontaneously, in case of rain, one would like to take refuge under it. Don't do it! This tree produces a sap that causes significant burns. You can identify this tree because its fruits resemble apples. Moreover, it is often marked with a red cross on the trunk. If you are a fan of snorkeling, be vigilant of sea urchins and lionfish whose dorsal spine is venomous.
