September in Croatia is when summer is in its twilight but the weather is still spectacular with ample opportunity to enjoy pristine coastlines and abundant nature. This is the time of year when holidaymakers are few and far between and the presence of locals in coastal destinations is also sparse as they start migrating inland. Therefore, traveling to Croatia during this month will be easier on your wallet. This is the best time to lounge on the beaches of Split or walk along the ancient city walls of Dubrovnik, meander the boardwalks over Plitvice Lakes or delve into baroque traditions in Varaždin.
