The cleaning event Čisté hory (Clean the Mountains) takes place every year after the summer season is finished. 2020 is the 42nd year of the initiative that took place on the last Saturday in September.

The weather was not very good that day so many volunteers decided to go in the days following.
Altogether 480 volunteers participated in the event in areas of the Tatra national park and Pieniny national park, where they collected 355.5 kilos of the rubbish in total, the SITA newswire reported.
“Even though we are not happy that after years of these events, there is still something to collect, personally, I am very glad that there are enough people who have a cordial relationship with the Tatras and generally towards nature,” said Igor Stavný, a coordinator of Čisté Hory, organised by the State Forest of the Tatra National Park (TANAP).
