Mauritius asks for a yellow fever certificate only if you are arriving from, or have transited through, a country where yellow fever is present. For most visitors no vaccination is compulsory, but routine cover such as tetanus, measles and hepatitis A is worth checking with your own doctor a few weeks before you fly.
Bring prescription medication in its original packaging, with a copy of the prescription or a short letter from your doctor, and pack enough for your stay plus about a week. Some medicines that are routine at home are restricted or simply unavailable here, so ask us before you travel rather than after you land.
The island is warm and humid for most of the year, and almost everyone underestimates the first forty-eight hours. Slow down on day one, drink more than you think you need, and keep the hardest walking or sport for the early morning.
