To the north-west, the mountain dips its slopes in the sea with beautiful cliffs all along, overlooking on the east the marshes of Txingudi, the river Bidasoa and its mouth (tracing the France–Spain border) as well as the towns of Irun, Hendaia and Hondarribia on the riverbanks.

The area is a relevant landmark on the grounds of its strategic position close to the border with France, with the range standing as the easternmost Spanish rise by the seaside and affording an unmatched view miles away, both over the sea and inland.

As a result, the military has always showed an interest in the place since the 16th century when the Spanish-French border started to be drafted, taking to building defence facilities, such as the towers dotting the ridge (dating from the Carlist Wars) or the Fortress of Guadalupe going back to 1890, nowadays out of use.

A demanding route to the top sets out from the Santo Cristo of Lezo, with the path ascending steadily across the southern side of the range roughly eastbound till it gets to the ridge and joins the GR-121 near one of the towers dotting the outline of the mountain.

The long route GR 11 cutting its way through the southern side of the Pyrenees to the Mediterranean departs from the Cape Higuer at the north-eastern tip of the mountain range, with the first kilometres running by the seashore into Hondarribia.
