The two cities have a very good transport link (with a bus line going every 20 minutes). The history of Omiš is long and very interesting. On such a small locality, you can visit a variety of cultural and historical sites (churches that date from X. to XVIII. century, plenty of monuments, forts, museums etc.)
Today, Omiš and its surroundings are focused on development of tourism and thanks to the nature around it, it has a significant place in Croatian tourism.
