Split is a lively city with a rich history, set on a peninsula surrounded by mountains. It is Croatia’s main coastal city and airport, and the gateway to the Dalmatian islands, but Split itself should not be overlooked as a great place to explore. A must-see is the stunning Diocletian Palace built in the 3rd century, a UNESCO World Heritage site. It is a Roman walled city within a city which has been beautifully preserved for centuries with houses, shops, bars and restaurants. Split also has a great cultural scene with regular festivals, lots of museums and markets. There are some great beaches and fun nightlife.
