Forget Game Of Thrones and Dubrovnik just for a moment. As the second-largest city in Croatia and the capital of the Dalmatian Coast, Split is a gorgeous Croatian gem that's equally worthy of attention. At the city's center sits a mesmeric ancient Roman palace, attributing to its old-world historic feel that charms visitors time and time again. But whilst the town center is a beautiful place to spend a day or two, the outskirts are mostly suburbs with not a lot going on.

But what many tourists don't know is that Split is actually perfect as a base for trips to surrounding islands and national parks. Home to one of the busiest harbors in Europe, the city plays a central role that connects all of Croatia - a role that allows for amazing day trips to other incredible parts of the southern Croatian coast. With dozens of islands to hop to, stunning national parks to explore, and plenty of historic, entertaining towns and cities to discover from Split, it's truly a destination for Croatia-bound travelers seeking out the best and most famous attractions in the country.

7 Blue Cave

3 Scuba Diving

Surprisingly, Croatia is an amazing scuba diving destination. Although it's not the most popular activity in the country, it's definitely worth trying - especially when in Split. The water is crystal clear, which makes for excellent dive conditions with plenty to see.

This means that at any given dive site, it's highly likely that divers have the entire underwater world all to themselves. As diving in the area is still growing and developing, dive centers in Split are few and far between. But they do exist - and one of the most well-reputed is Split Diving.
