Park in the Hospice car park at the Col du Petit Saint-Bernard.
(S/E) Take the signposted path: Lac sans Font-Lancebranlette heading north-west behind the Petit Saint-Bernard Hospice.
(1) Cross the Torrent du Reclus then climb the winding path through the mountain pasture to the junction with the path to Lac sans Fond (a sign).
(2) Leave the path leading to Lac sans Fond on your left. Head straight on towards Lancebranlette and continue across the mountain pasture towards the north-west until you reach the base of the schist outcrops.
(3) Continue across the scree to the right of a rocky ridge; it is steep but stabilised by logs. Reach the grassy saddle on the west face of the summit. Continue via wide switchbacks across the grassy slope until you reach the edge of the summit ridge. Pass the orientation table and a bench; a break by the orientation table offers an ideal view of Lac sans Fond below. Then reach the summit of Lancebranlette.
(4) Follow the same route back as on the way up to return to the Hospice car park at the Col du Petit Saint-Bernard (S/E).
