Sao Tome & Principe: 8,000 tourists Why so few? It may take a while to get there.
Why you may still want to visit? It’s so remote you are more or less guaranteed proper peace. And there are both stunning beaches and mountains that invite for hikes and photo oportunities. Do try the street food.
What else? Bring cash and do get your return ticket sorted before you visit. You can easily walk to the airport from Sao Tome.
