 In 2019, Orcières-Merlette hosted a "colour" skiing event, which involved being sprayed with coloured powders whilst skiing down the mountain. A 2020 Alpine Skiing Europa Cup Super-G event scheduled to be held at Orcières-Merlette was cancelled due to heavy snowfall and lack of visibility.
 Orcières-Merlette was first used as a Tour de France stage host in 1971 edition, when it was used for the finish of stage 11 and the start of stage 12, including the rest day in between the stages. Luis Ocaña won stage 11, attacking from a group of leading contenders and soloing for the final 60 km (37 mi). He also gained the yellow jersey as leader of the general classification with a finishing margin of 8:42 minutes over the former leader Eddy Merckx. Merckx had won the previous year's race. Following the rest day, stage 12 of the 1971 Tour started with a descent from Orcières-Merlette, which Merckx attacked on with a small group and remained in the lead to the finish in Marseille. Ocaña led the chasing peloton (main field) to limit his loss to Merckx on the stage to two minutes. The leading group broke the record for the fastest average speed of a mass-start Tour de France stage at 45.351 km/h (28.180 mph).
 The Tour returned to Orcières-Merlette the following year when it was again used across a rest day. Lucien Van Impe took victory at Orcières-Merlette in the initial stage 11. The next time Orcières-Merlette was visited by the Tour was ten years later in 1982, when it was used for the finish of stage 15, won by Pascal Simon, before hosting the start of the next stage.
 Orcières-Merlette featured in the 1989 Tour as the finish of stage 15's individual time trial, which was won by Steven Rooks. The yellow jersey was taken by Greg LeMond, in a Tour considered to be one of the greatest in the race's history. The stage also included an ascent of the Col de Manse mountain pass, which stands between Gap and Orcières-Merlette.
