Loads of rubbish have been dumped down a crevice at Majjistral Nature Park, and removing it is problematic, the park said.
The park is a Natura 2000 site.
The rubbish dumped down the crevice includes bulky items such as computers, mattresses and iron poles.
"Due to the nature of the area it is very difficult to clean the place, and the management will seek best options how to clear the area," the park said.
