Saint-Luc has a ski resort above, at a mean elevation of 2,200 metres. Connected with Chandolin's ski resort, it forms the Saint-Luc - Chandolin Ski Domain, with 12 ski installations (8 skilifts, 3 chairlifts, and 1 funicular), as well as 65 kilometres of ski runs. The main points of "rendez-vous" of the station are situated either at Tignousa, at an elevation of 2,180 metres, or at the Tsapé, in Chandolin side, at an elevation of 2,475 metres. The lowest and highest points of the station are at 1,680 and 2,965 metres respectively, both located on the slopes of Saint-Luc.

The resort started in 1959, with the ski lift Combettaz., which was subsequently replaced with a chairlift in 1964, constructed by GMD Müller. On the same occasion, it built the main lift of the station, Tignousa. Preceding these constructions, Chandolin had already built a Poma skilift in 1961, named Illhorn, which brought skiers from the village to the summit of the peak of the same name. In 1965, Müller built the Par-di-Modzes skilift, situated left of the Combettaz. Designated for young skiers, the skilift would be shut down in 2018. The following year, Poma built the Foret skilift, located left of the Par-di-Modzes skilift. Named after the forest it travelled through, the skilift suffered many renovations and enlargements before being replaced with a Poma chairlift in 2015. Two years later, the final Müller lift in Saint-Luc, the Col des Ombrintzes, was put into service. No further constructions or renovations were effectuated until 1971, when Chandolin ordered Willy Bühler company to construct the Tsape chairlift (also known as La Remointse) and the Etables skilift. In 1973, to open access to the Bella-Tola sector, the ski lift Pas de Boeuf was put into action. With a route of over 2 kilometres long, it became the longest Poma installation in Switzerland. Apart from the renovations on the Foret skilift, Saint Luc - Chandolin waited for eight years before ordering the construction of their next installation in 1981, with the Cret de la Motte poma lift. Not a very interesting lift for skiers, it was put out of service and abandoned in 2012. The subsequent year, the Bela-Tolla skilift authorizes the access to the peak of the same name, which becomes the highest point of the resort. Although the peak's elevation is 3,025 metres, the skilift is only capable to arrive 60 metres lower. In 1985, the Ecole (literal translation of School in French) lift is put into action for young skiers of the Ecole Suisse de Ski de Saint-Luc, and Saint Luc - Chandolin starts exploring a connection project between their two domains. In 1986, the Rotsé chairlift, built by Müller, permits for the first time skiers from Chandolin to access Saint-Luc by ski. To grant the return of Chandolin skiers onto Chandolin, the Col des Ombrintzes skilift is lengthened by Poma. Seven years later, in 1993, the Illhorn skilift is renovated and cut into two separate segments, as the previous lift was very difficult and especially long. The Illhorn I lift is a simply shortened version of the old lift, while Illhorn II is built from completely new materials by Poma. The following year, the Combettaz chairlift is replaced by Funiculaire St-Luc – Tignousa, a funicular built by Garaventa, which was supposed to promote "durable installations". At the same time, Poma builds a skilift, similar to the Ecole, in Chandolin, and is named Tsa. After that, no more installations were built, excluding the replacement of the Foret lift in 2015 and the shortening of the Rotse in 2020.

In the 1970s, an action television series called Skiboy was filmed in Saint-Luc, where actors Stephen R. Hudis, Margot Alexis, Robert Coleby, and Frederick Jaeger starred in the show. The show is about a young skier who solves crimes and mysteries in his village innocently.
