The journey of the Cremallera de Vall de Núria, most often just known as the cremallera railway (“zipper” in Catalan), built in 1931, is spectacular: the little train follows the rushing Ríu Freser and then, quite suddenly, begins to scale steep mountainsides along stomach-churning switchbacks, from where you’re rewarded with beautiful views of the river and valley far below. Trains depart from the Ribes-Enllaç station, in the southern part of Ribes, daily year-round except November, when it’s closed. In high season (July to mid-Sept, plus winter hols), trains run 10–13 times a day; in low season, it’s around 6–7 times. One-way journey time is 35 minutes; tickets are €21.25 round-trip in high season, €17.75 in low season. For the latest information, visit wvalldenuria.cat or call t972 732 020.
