The route starts in Dalt Square in Erill la Vall, following a traditional footpath that descends to the road leading to Boí. Take extra care as you pedal along the road for about 300 meters until you reach the beginning of the Cultía trail. From here, the trail ascends steadily, with a consistent and manageable gradient. After crossing the Planamolín Ravine, the trail winds through a series of short, continuous switchbacks within the peripheral protection zone of the Aigüestortes and Estany de Sant Maurici National Park. It continues past the head of the Ribampiedro Ravine, ending in the meadows near the Erill or Basco Huts. The descent follows the same route.
