In the tourist towns near the capital (Gosier, Ste-Anne) and anyplace there’s a large sailing community (Deshaies, St-François) a visitor can get by with just some basic French expressions. For exploration further afield a good command of basic French is very helpful. A phrase book is a great idea.
Teach English abroad with an i-to-i TEFL Course
If you’ve ever thought about living and working abroad, then why not teach English as a foreign language (TEFL)? It could be the key to funding your travels and experiencing new cultures in a totally new way. You don’t need teaching experience or even the ability to speak the local language – although you might learn it while you’re out there.
