The northern and southern side are clearly delimited by a rocky limestone crest running east to west up to the summit, which is almost entirely bare rock.

Larraitz, lying at 403 m (943 m below the summit), harbours the long picnic area and car park Zamao, with a couple of café-restaurants (former farmhouses) and a hermitage (17th century) all surrounded by gentle fields.

Next, it cuts its way straight across the southern side of the mountain along a pine tree plantation on the right till the spring Oria is reached at a sharp bend.

This time the same track may be followed in the beginning for a convenient and gentle stroll, until a winding slope is overcome some minutes before the turning of the crest (milestone Gazteraztegi, 520 m).

Right before the final slope to the aerial, a narrow path bounds south-east on the left into the tough and vertical valley carved by the stream Muitze (waterfalls on the way).

The meeting takes place in a cheerful environment, with numerous public, traditional music (trikitixa) enlivening the atmosphere and stalls featuring rural produce, e.g. cider and cheese, as well as crafted products.

On June 29, Saint Peter's day, a big and popular religious celebration is held at the hermitage (a gathering called erromeria in Basque).
