Guadeloupe is part of France, which is part of the EU, so all related immigration rules apply. US, Australian, British, Canadian, and other EU citizens do not need a visa, just proof of a return ticket and a passport. You also no longer need a visa if you already have a long-stay visa from a Schengen state. Contact your consulate if you are visiting Guadeloupe for reasons other than tourism.
Health and Safety
Guadeloupe provides a good standard of healthcare to its residents, but you should have travel or health insurance to cover possible treatment costs and emergencies. There are clinics all over the island, but only major centers like Pointe-a-Pitre and Basse-Terre have larger hospitals.
Water is relatively safe to drink because it is chlorinated, but sensitive travelers may experience a mild upset stomach. To be safe, buy bottled water. Dairy products and milk are pasteurized and fine to eat or drink. Fruits, seafood, poultry, and local meat are also okay.
Be mindful of schistosomiasis or bilharzia, which may be acquired by swimming in fresh water. Avoid any contact with the manchineel tree sap, which is toxic and burns the skin. Never take shelter under one, especially when it’s raining. They look like apple trees and often have red markings on the trunk to serve as warnings.
If you are coming from an endemic or infected country where yellow fever is present, you will need a yellow fever vaccination at least six days before you arrive. You can avoid dengue fever and mosquito bites by wearing protective clothing and using insect repellent.
Guadeloupe is a generally a safe travel destination because crime rates are very low, but of course, don’t leave your common sense behind. Don't walk in Pointe-a-Pitre alone after dark and wherever possible take only main roads.
