If driving or taking the train go to Moutiers. As you come in to Moûtiers look for signs to COURCHEVEL / MÉRIBEL on the D117, follow these and filter right. From here LA TANIA is signposted. Stay on this road for about 10km past the turn off for Méribel and Brides Les Bains, through La Perrière until you come to a small roundabout and go right (almost back on yourself) - signposted Courchevel / Le Praz / La Tania.
