The first ascent of Lyaskovets Peak was made on 14 December 2004 by Lyubomir Ivanov and Doychin Vasilev from Camp Academia (541 m) during the Tangra 2004/05 Survey. Their route (UIAA grade III) started with 4 km of solid but crevassed firn surface ascent up to Catalunyan Saddle (1,260 m) on the main crest of Tangra Mountains, from where they traversed the precipitous west slope of the peak until the north slope was reached, from where the summit - itself split by a crevasse - was easily reached.
