The A Groba hills are located very close to the coast of Baiona and Oia, and are therefore the site of numerous observation points in high positions with fine views of the sea.

One of these is O Cortelliño, a recreation area with an observation platform reached via a wooden walkway, with views of Vigo, Pontevedra and Arousa, and even Fisterra on a clear day.

From its location in the magnificent natural surroundings of A Groba, the villages of Baiona, Nigrán, O Val Miñor and Monteferro, and the Cíes islands at the mouth of the Vigo estuary can be clearly seen from here.
