Trogir  is a historic town and harbour on the Adriatic coast in Croatia, with a population of approximately 13,000. Today it is part of the greater Split metropolitan area or conurbation which numbers over 400,000 inhabitants. It is on the UNESCO World Heritage List as it is one of the best preserved medieval towns in Europe. It is a fascinating place to just wander and also contains a range of accommodation. At present the town is undergoing considerably redevelopment, but it far from fully developed and you will still find run down or even abandoned houses. It is definitely worth the day trip from Split.
Trogir is in the immediate vicinity of the Split airport and about 25 km (30 minutes by car) from the centre of Split. From the airport take the regular 37 bus (runs every 20 minutes during the day and every 30 minutes in the evening and on Sundays, cost 20 Kuna). The 37 bus is the regular Split-Trogir service and you can use this bus to get to Trogir from Split (or vice versa). It is also relatively cheap to catch a taxi from the airport to Trogir.
The old part of Trogir occupies an island which you can walk around in about 20 minutes.
You can also rent a car. 
Stunning beaches, spectacular islands with lavender-covered hills, small medieval and renaissance towns and Roman ruins characterize the intriguing strip of land that comprises Central Dalmatia. Warm Dalmatian hospitality and cheer is sure to capture your soul as you explore the quaint towns and old fishing ports.
Trogir is a jewel of a town encased in 15th-century walls. Tiny medieval streets wind through the enchanting town revealing hidden restaurants and eye-catching galleries. A wide seaside promenade snakes around the town, culminating in a charming port full of sailboats waiting to take you to the islands of Drvenik Mali and Drvenik Veli with their pristine sand beaches and secluded coves. Stretching out from the main land of Trogir to either side is an infinite number of beautiful beaches as well. A pleasing blend of Romanesque and Renaissance architecture, Trogir boasts a spectacular Venetian Cathedral of St. Lovro, a 15th-century town hall, the Church of St. John the Baptist with its gorgeous carved portal. Trogir is a delightful little town that is conveniently located to explore Central Dalmatia.
Just a short drive away, visitors may explore the intriguing city of Split with its busy commercial port, residential houses, shops and restaurants all rising from the incredible ruins of Diocletian’s Palace. The ancient ruins of the Roman city of Solin are also just a short drive away from Trogir and make an extraordinary day trip.
About 3km from Trogir, on the island of Čiovo (connected by the bridge) is a town called Okrug Gornji. It has 1km long beach with lots of bars right next to sea. If you like having a drink on a beach, jumping in the sea from the bar or a good night out then this is the place for you.
Note about islands of Drvenik: although they are very beautiful and well worth the visit - DO NOT eat in restaurants there. They are extremely expensive (one pizza for about 15 euros); carry food and water with you.
In Poljica you can take peaceful evening walks free of modern day noise. In the village you can find a restaurant, shop and cafe bar. Peaceful place for leisure time on the reach of attractive destinations (Trogir, Split, Šibenik, etc.).
