The village was rated weather resort in the 1930s and people came here to recharge, visit the monastery of the Grande Chartreuse (which was open to the public between 1903 at the expulsion of the monks to 1940 at their return from Italy).

It was also at St. Pierre that created first "Syndicat d'initiative" of France, now best known under the name "Office du Tourisme" (tourist information centee) and thanks to an Alsatian called Leon Auscher, who had adopted this country that was so dear to him.

Snow is sometimes random and allows seasons of no more than three months, but the resort's strategic location near major urban centres (including Grenoble), the approximation of the neighboring station Planolet, the family atmosphere, and the affordable prices made it experience in 2005 and 2006 its largest turnover in terms of selling packages.

The Saint Pierre de Chartreuse / Le Planolet ski resorts include : 35 km of slopes, 4 black, 9 red, 5 blue and 6 green.

The bottom of the station is situated 900 m, a drop of almost 900 m. Depending on snow conditions, the resort features a snowpark (located on the old departure of the chairlift Battour), and various spots on the Scia (Big Air in the first ledge and various bumps on the last run of the track).

The ultra-running race "Le Grand Duc" (named after the Eagle Owl which is the symbol of the Parc Régional Naturel de Chartreuse) starts and ends in the village with a route which varies each edition.
