The Caribbean
Can you drink the tap water in the Caribbean?
Last reviewed September 2026
The Caribbean is a patchwork. Some islands run modern, drinkable supplies; on others, and especially outside the main resort areas, bottled or filtered water is the safe default. On our index the 13 countries in The Caribbean average 53/100 — but that average hides a wide spread, from Barbados (72) down to Haiti (16). Scores above 70 mean tap water is generally safe to drink. 40–69 means treat it with caution — filtering or bottled water is wise. Below 40 means it’s best avoided straight from the tap.

Traveling in the Caribbean: what to do about tap water
Because the range across The Caribbean is so wide, the safe rule is to check the specific country before you go rather than assume the region is uniform. In any country scoring under 70, treat the tap water — a rolling boil handles microbes, a certified filter or sealed bottled water covers the rest, and it is worth being cautious with ice and raw produce too. Where a country scores 70 or above, the tap water is generally safe to drink and a refillable bottle is the cheaper, greener choice.
