The official first ascent of Mont Blanc du Tacul was by a guideless party comprising Charles Hudson, Edward John Stevenson, Christopher and James Grenville Smith, E. S. Kennedy, Charles Ainslie and G. C. Joad on 8 August 1855. However, Courmayeur guides may have already ascended the peak during their attempts in 1854 and 1855 to force a way up Mont Blanc from the Italian side.
