Transfers to the Apartment
Remember that you must collect and drop off your keys from our local agents offices which are based lower in the valley in Les Allues. They are directly on the main road to Mottaret but the main coach companies will not typically stop there. You will need to get the local resort bus back down to collect keys making bus transfers a bit more hassle.
