You don't need buses to visit Split, but if you want to get to the airport, or visit Trogir or the Roman ruins at Salona, then you'll need to figure them out. Basically bus 37 takes you to the airport, and carries on to Trogir, and bus 1 will take you to Salona.
The station is quite central, about 800m north of the palace. Some maps seem to put it down near the train station, but that doesn't seem to be the truth. The actual bus station is on Domovinskog Rata. If you walk from the Riva Promenade towards the station, cross the bridge over the tracks, and then take a left up the huge Zagrebacka road, you'll get there eventually.
The main mode of transport for a lot of people of the city is bus. One reason is that parking is so non existent that you could drive around for hours looking for a place. We did do that for about one hour on the first day, and that was the end of that. They charge a lot to park, and the bus comparatively is around $1.50 each way to a spot anywhere in the zone one. Zone 2 costs $2 one way, and $3.5 round trip. Zone 4 is farthest out and that runs $3.5 to $5.50 for round trip. . The main bus station is on Zagrebacka, right at the Diocletian area on the east side. That also is right close to the rail and boat traffic pickup/drop off points, and is called Trznica.
There are 3 different buses to the airport:
1. The Croatia Airlines bus: For the timetable you need to go to the airline office in town to find out.
2. The local bus no. 37 that takes you to Trogir will stop right by the airport. It leaves from Sukoisanska.
3. The private airport bus which costs 30 Kuna and leaves from the same spot as the Croatian Airlines bus ie at the beginning of the Riva in front of the restaurant there sort of opposite the Green Market. For the timetable you will have to go the the tourist agency on the Riva, the timetable is hanging in their window or just ask the drivers when you check out the spot and a bus is there.
forget the expensive taxis and use the No. 37 Bus when using the Split Airport. The bus station is straight ahead when walking out the airport door ... 150 meters directly across the car park ...walk towards the ocean if you can see it. The trip to Trogir to the west is around 5 minutes and about 35 to 45 minutes to the center of Split. I am uploading pics. of the airport ( in Croatian - Aerodrom ) that you know when to get off. Do NOT , I repeat do NOT rely on the bus conductor or driver to tell you to get off...they won't. Cost from Trogir was 11 Kuna this Summer 07. From Trogir or split you can get intercity buses just about anywhere. Buses leave Trogir for Split starting at 00H50 running aprox. every 40 min. From am 6H00 to 21H00 busses leave every 20 min.. after 21H40 buses leave around every 40 min .... Last bus from Trogir is at 23H30. The schedule from Split to Split Airpoprt are aprox. the same. BEWARE .. there are dodgey types around the bus stations operating as unofficial taxis ...use at own risk.
Bus from Trogir to Split Airport leaves from platform 8 of the central bus station which is on the main road opposite the Konzum supermarket. Expect to get out as soon as the2nd stop ( as one stop could be left out ). There is no time to relax on this trip..you need to be on the lookout for the airport which is on the left side of the road when Trogir is behind you.
Local transport is served by a network of buses with 20 lines within Split and an extensive network of interurban buses that provide fast links with surrounding towns of Solin, Kastela and Trogir on the north-west and Stobrec, Podstrana and Omis on the eastern side of the Split connurbation.
The area is divided into 4 fare zones, but if you intend only to travel within Split you'll be in the first zone. You'll find a map of fare zones here: www.promet-split.hr/zone.htm
Most of the bus routes pass through three main bus stops in center of town: "HNK" in front of the Theatre, "Trznica" close to the main open-market place and "Opcina" further to the north in Domovinskog rata street. Their intervals range from every 10 to every 30 minutes, depending on the line and time of the day. You'll find all schedules here: www.promet-split.hr/grad.asp
Single tickets are sold by drivers, but if you buy ticket for 2 rides at the Promet kiosks it will be cheaper per one ride.
The prices are: 8kn for a single (12kn for a double-ride ticket) for one zone, 10 (16,50)kn for 2-zones, 14 (21,50)kn for 3-zones and 18 (28,00)kn for 4-zones.
In all zones children up to 6 years can go for free, and between 6 and 10 years pay a children's ticket that costs 3kn.
Local buses :
Buses no: 37 go to Solin, Split Airport & Trogir.
The local bus station in on Domovinskog, about 1 kn north east of the city centre.
It is in Lovret area.
Please refer to the website below for better infos.
This is just a note of caution in case you decide to take the bus from Split to Trogir and back again. The bus to Trogir leaves from the bus station near the ferry dock and the train station. On the way back to Split, the bus stops at a station south of the city center of Split. It doesn't go to the main bus station. Just know that you are south of the city, and if you continue north, you will run into the Gregorious of Nin statue in about a mile.
