This year, they are organizing once more a Volunteer Hiking Holiday! The idea is to create a 60 km long scenic hiking trail along the backbone of Ikaria, the ridge of the Mount Atheras, running all the way from the East to the West end of the island – the Transikarian Trail, also called Atheras Ridge Walk. OPSIkarias are in charge of this project, as they have started this voluntary work already some years ago and they are working on it on a continuous basis.
