The Arbaiun Gorge, at the bottom of the Pyrenean valley of Salazar, between Lumbier and Romanzado, is the longest and most stunning of all the gorges in Navarre. The river Salazar has cut the rock away over the centuries, giving rise to an unparalleled spectacle. Imposing vertical walls run for almost 6 kilometres.
A diverse and peculiar vegetation grows inside the gorge providing a variety of seasonal colours of great beauty. On its rocky outcrops there is a huge colony of griffon vultures, which you can see flying if you lean out over Arbayún from the viewpoint at Iso. This immense natural wealth has led to the Arbaiun Gorge being declared a Nature Reserve and also a Special Protection Area for Birds.
