Di Duca, Marc: - Marc has been a full-time travel guide author for over two decades, during which he has contributed to almost 200 guides to destinations as diverse as Siberia, Brazil and the Caribbean for all major travel publishers. Based in the Czech Republic, Marc is a regular visitor to the Balkans where hiking in the remote and largely undiscovered mountains of Northern Albania comes a close second to lounging on the beaches of the Adriatic as his favourite activity.
