You can take the C shuttle to the centre, then switch to the A shuttle to the Aquacime, or go there after a nice snowshoe or normal walk through the forest (25 minutes). This pack includes collecting 3 people at the chalet, taking them to Aquacime, entrance fees (17 eur) and back 2 hours later.
Please note that boxer-type swimsuits are prohibited, only speedos allowed for men (dispenser available on site).
