The Arousa estuary is considered one of the richest marine zones in the world, uniquely productive thanks to the quality of its waters together with other factors such as the temperature and estuary currents.

The Cruz de Lobeira lookout point enjoys views of the estuary and the Illa de Arousa to the west, with the O Barbanza mountains behind them. Looking to the east, wide swathes of the province of Pontevedra can be seen, while to the south lie the O Salnés peninsula and the island of Ons, part of the Parque Nacional das Illas Atlánticas (National Park of the Atlantic Islands).

Monte Lobeira has two spaces designated as lookout points, but the most spectacular views are found at Cruz de Lobeira, the site of an ancient settlement where archaeological remains of the castro and burial mounds can be seen.
