Ozersk is a city in the Chelyabinsk region in Russia. The city is closed to tourists. Because in Ozersk there is a plant for the production of nuclear weapons components. The city is surrounded by beautiful lakes: Irtyash, Kyzyltash, Malaya Nanoga and Bolshaya Nanoga. My friend sent me these amazing pictures of Lake Irtyash. I'm happy to share with you the beauty of the sunsets in Ozersk.
