Duce is situated in the middle Dalmatia, within the riviera of Omis, only 20 km from Split towards Makarska.
Duce extends along the coastline of the Adriatic Sea, between Dugi Rat and Omis, with beautiful beaches which are around 4 km long, and only 2 km from the estuary of the river Cetina.
Slopes of the mountain Mosor are found all over the northern part of the Duce. The height of the slopes is around 400 m, measured from the sea level. Slopes are overgrown with dense forests, which on some places even go all the way down to the sea.
