Dubrovnik is about 230km from Split, and a return day trip covering both the drive and a real look at the city walls runs to around 12 hours door to door – a long day, but a genuine way to see one of Europe's most famous medieval cities without adding an overnight stop.
The route
The drive used to mean crossing briefly into Bosnia and Herzegovina at Neum, a narrow strip of Bosnian coastline that splits Croatia's own coast in two – passport required, border queues included. Since the Pelješac Bridge opened in 2022, the main route bypasses Neum entirely, so most organised day trips no longer involve a border crossing at all. The older Neum road still exists if you're curious, but there's little reason to take it over the bridge now.
Is the long day worth it
If a dedicated stay in Dubrovnik isn't part of your trip, this is a real way to see the city walls and Old Town without it. It's worth being honest about the trade-off, though: with roughly six to seven hours spent travelling, the time actually spent in Dubrovnik itself is a few hours, not a full day's worth. If your schedule has any flexibility, splitting the two cities across separate stays – or spending at least one night in Dubrovnik – gives a far less rushed visit. If 12 hours feels like too much for one day, Krka National Park is a shorter, closer alternative for a day trip from Split.
Booking
A guided day tour from Split bundles the return transport into one booking, which is the main advantage over arranging a bus or rental car yourself for what's already a long day. Book at least a few days ahead in peak season.
