Colombia (Cartagena)

Cartagena’s walled Old City boasts UNESCO World Heritage status, candy-colored colonial buildings, rooftop bars with Caribbean sunset views, and ceviche that rivals Peru’s best—all at pocket-change street food prices. A boutique hotel in the historic center runs $60-80 per night, a price that would cost four times as much in a comparable European capital, outperforming #4 Georgia (Tbilisi)’s $10 feasts but offering more polished luxury. Average meal costs of $5 save you 60% versus similar Caribbean destinations.
