White beaches, turquoise waters, and lively nightlife — these are images Bridgetown, the capital of the Caribbean island of Barbados, likely conjures up in the minds of most. But Bridgetown is so much more! There's the colonial heritage — its entire downtown is on the UNESCO list, after all — lush forests right outside city limits and an abundance of local and international shopping options. An animated buzz sets in as the sun goes down, inviting one to join the famously laid-back and welcoming Bajans on a night out.

Durban moves to the beat of gqom, its own home-grown music genre, which is slowly making its way onto global charts from South Africa's sunny, tropical melting pot of eclectic cultural influences.
