Health
Martinique is a tropical, low-altitude French Caribbean island: plan for heat, strong sun, rain and dehydration, especially when hiking, sailing or during Carnival crowds. Use safe-food habits; treated water is generally available in developed areas, but use bottled/treated water if unsure or outdoors. Prevent mosquito bites because dengue and Zika occur; CDC also flags tick-borne and water/soil risks. Avoid floodwater/mud after heavy rain and avoid swimming in fresh, unchlorinated lakes, ponds or rivers because schistosomiasis is reported.
Vaccinations
Reference only: consult a doctor or travel clinic at least a month before travel. CDC advises being up to date on routine vaccines, including MMR, polio, Tdap/Td, flu, varicella and shingles as applicable, plus COVID-19. Hepatitis A is recommended for unvaccinated travelers, hepatitis B for unvaccinated travelers of all ages, and typhoid for most travelers, especially rural/smaller-city or home-stay trips. Rabies pre-exposure vaccine is only for higher-risk activities or limited access to care. Yellow fever vaccine is not recommended for Martinique; proof is not required from the United States, but is required for travelers age 1+ arriving from, or transiting more than 12 hours through, a yellow-fever-risk country.
eSIM / connectivity
Connectivity is generally good in populated/coastal areas, but coverage can thin in mountains, beaches and rural coves. Local mobile networks include Orange Caraïbe, SFR Caraïbe, Digicel and Free Caraïbe. eSIM is supported by some operator and travel products, including SFR Caraïbe eSIM and Orange Travel-style eSIMs; confirm your phone is unlocked/eSIM-capable and check current local prepaid availability before arrival. Physical SIMs and recharges remain useful through carrier shops and authorized retailers.
