Mugarra is a peak of Biscay, Basque Country (Spain), 936 m high, belonging to the Aramotz massif.

Mugarra continues the line of the Anboto, Alluitz, Aitz Txiki and Untxillaitz and is the eastern limit of the Aramotz massif.

Huge limestone rock where fossil rests of seashell can be found.

This limestone crest is being consumed by a great quarry that causes irreparable damage to the mountain and is bordering the protected area.

In Mañaria (181 m), a good path reaches the Mugarrekolanda (760 m) col. From the col an easy route leads to the summit from the west.
