The Mont Tout Blanc is located on the ridge dividing the Valsavarenche valley (East of the mountain) from the Rhêmes valley (West), both on the right-hand side of the Aosta Valley. The Aouillé pass (Col de l'Aouillé) divides it from the neighbouring Pointe de l'Aouillé (3,445 m) while the Col Rosset divides the Taou Blanc from Punta Leynir.
