With no accommodation at the ski area itself, all visitors approach Arcalís via the CG3 road along the picturesque valley from Ordino.
Vallnord's ski-bus service
runs from Andorra la Vella to La Massana, and vice versa; then runs from La Massana to/from Arcalís, via Ordino. The company also operates a line connecting La Massana with Arinsal (via Erts).
Most tour operators also organise excursions from Arinsal and La Massana, but the most convenient way to reach Arcalís is with your own vehicle or in a rental car.
