Trogir is also a UNESCO Heritage Town and just 37 kilometres from Split – next to the airport. The cheapest way to go is by Bus route 37. Trogir is picture perfect, compact and pedestrianised and can easily be seen in half a day. You can explore intricately carved palaces, churches, Renaissance gates and medieval streets. Don’t miss the 13th century Cathedral of St Lovro; the “Old” and “New” Cipiko Palaces both in the town square; and the 14th century Genoan Kamerlengo Fortress.
Tip: The 37 bus is the cheapest and quickest way (apart from taxi), but we love taking the local ferry one way for the views of the Island of Ciovo and the Split coast. The Bura Line Ferry runs up to 6 times a day in Summer and stops at Slatine where you could hop off for the lovely beach if you time your ferries right.
We also suggest a day trip to the amazing Krka Falls - but unlike the two trips above, it's cheapest and easiset to take an organised trip.
