Most activities in the resort are organised outdoor excursions. For swimming pools, fitness centres and similar you need to pop up to neighbouring Les Menuires.
In St Martin dog sleigh rides, pulled by eight dogs and driven by Emmanuel Colire, an experienced musher, takes passengers along the Doron path that follows the river of the same name. Two options are on offer, a shorter thirty minute circuit or an hour long trip including a visit of the Burdin Mill.
Guided torchlit discovery tours of the Belleville Valley's specialities and traditions are organised at nightfall.. The Vallée des Belleville has two magnificent Baroque churches, the one in Saint Martin church and the other the Notre Dame de la Vie Sanctuary, situated on the side of the road between Saint Martin and Les Menuires. Every Wednesday, the FACIM (Foundation for Cultural Action in the Mountains) organises guided visits of these two monuments.
Snowshoeing is also possible, starting from Les Menuires but with shuttle bus from St Martin and snowshoe hire included in the local price. There are four kilometres of paths for snowshoe outings with a panoramic view of the Vallon du Lou and the Masse mountain ranges. Start from the top of the Mont de la Chambre and walk down to the resort. Access to the departure is possible using the Bruyères cable car (for which a lift pass is necessary). The Ski School organise a different outing with a guide, next to the hamlets of the valley every day.
