On 23 May 2010, Lunger became the youngest female climber (aged 23 years, 11 months, and 17 days), to have reached the main summit of Lhotse. In February 2015 Tamara tried to climb Manaslu together with Simone Moro, but abandoned the climb due to heavy snow. During the 2015-2016 winter season, in her attempt with Simone Moro for the first winter ascent to the Nanga Parbat, she gave up just 70 meters below the top. In February 2018, along with Simone Moro, she made the first winter ascent of Pik Pobeda (Chersky Mountains, 3.003m). This summit is located in Siberia, in a very remote region. It is known to be one of the coldest places on Earth.
