This beautiful hike follows a Way of the Cross to the Hermitage de la Trinidad, continuing along the Trinidad ridge to the Arcos de Lumbier. These two impressive natural arches are called the Elephant Face and the Stone Arch. After the steep descent, you continue through the impressive Lumbier Gorge, carved by the Irati River. You'll follow the old railway line that cut through the gorge, passing through two short tunnels and along wide paths along the river. Be sure to spend some time in the gorge to observe the griffon vultures that nest in the rock walls.
