The pass known as Arreteneta, on the SE side of Onyi Mountain , features the Otsolepo Dolmen.

The Altxista pass, SE from the Argarate crags, includes the 8 Altxista cromlechs. The first hillock SE from the mentioned cromlechs houses the Altxista dolmen.

Hiking on the sierra toward the crossroads that, before reaching Leuneta, lead to Arano and Goizueta in the Urritzako Lepoa site, on the way to Leizaran, and 50 meters from the water dividing line, stands the Etzela W tumular cromlech. The Etzela pass presents the 16 Etzela cromlechs on the western part of Leuneta Mountain upon the water’s northern dividing line. 300 meters SE from the Etzela pass, near the Mandoegi track, there are two cromlechs, the Etzelako Arritxuriak cromlechs.

500 meters NE from Etzela, on the northern side of Leuneta and upon a steep hill that spreads over 150 meters, there is a set of 3 cromlechs and 2 tumuli known as the Unamene cromlechs.

Starting at that point, some of the most remarkable sets and examples stand in the lands of Navarre .

Returning to the Gipuzkoan part of the sierra and advancing towards Mandoegi, we will cross Abade Kurutz, where three cromlechs stood until the 60s, two of which had elevated stones.
