São Tomé & Príncipe: Cocoa Coast Adventures

The twin islands of São Tomé & Príncipe sit on the Equator, fringed by jungle and volcanic peaks. Highlights include:

• Snorkeling the Ilhéu das Rolas Equator line.
• Touring historic cocoa plantations (roças).
• Seasonal humpback whale migrations (July–September).

Getting there: Limited flights via Lisbon — book early for dry-season seats.
