A tourist visa is not needed for US citizens for stays up to 90 days in Grenada. It is recommended that your passport is valid for at least six months from your date of travel. Be sure to have at least two blank pages in your passport for immigration stamps. The same rules and recommended apply to citizens of Canada, the United Kingdom, Australia, and New Zealand.
Health and Safety
Grenada is a fairly disease free island; however, it is a tropical country, and is therefore advised to get the following vaccines four to six weeks before arrival: hepatitis A and B, typhoid, rabies, MMR, and tetanus-diphtheria. Grenada is devoid of yellow fever, and citizens from the US are not required to provide any proof of vaccines. Cases of dengue fever have not been reported for a number of years.
Grenada is generally a safe place, and the residents have always welcomed tourists with open arms and warm hospitality. Like anywhere else, keep an eye on your valuables, particularly when walking late at night or in isolated areas. Many parts of Grenada have no sidewalks and are poorly lit, so be careful of traffic and potential muggers. It is best to call a taxi from your restaurant or hotel instead of hailing one on the streets, although during the daytime the risk is substantially lower.
