Participants come from all over the world and most are second or third generation Croatian emigrants, Croatian ethnic minority communities in neighbouring countries and Croats from Bosnia and Herzegovina.
This year's host is Krapanj in Šibenik-Knin County. Participants will tidy up the island, including access to the beach for persons with disabilities, an old growth forest, and the seaside waters. The volunteer work is also envisaged to tackle drystone walls.
A variety of workshops and additional activities will be organised for the participants aimed at raising awareness of the natural and cultural heritage and the fishing traditions of this area, including a Croatian language and culture workshop, a media workshop, and excursions across the county, the HMZ said.
