Every second weekend in May, many lovers of Natural Heritage meet at the International days of minerals, fossils and the environment in Trzic for many years. In addition to expert Geological discussions, a sales exhibition of milled and untreated stones, jewelry and fossils is held.
Vsak drugi vikend v maju se v Tržiču na Mednarodnih dnevih mineralov, fosilov in okolja vrsto let srečujemo številni ljubitelji naravne dediščine. Poleg strokovnih geoloških razprav se vrši prodajna razstava brušenih in neobdelanih kamnov, nakita in fosilov.
