Islas de Gres

Islas de Gres is a natural area comprising six islands created by the Portodemouros reservoir on the Ulla River, situated between Vila de Cruces and Boqueixón. Five of these islands connect through footbridges and feature benches, barbecue areas, and a river beach suitable for swimming and relaxation.

The islands owe their existence to the construction of the Portodemouros dam, which flooded the Ulla River valley and created these natural formations. A medieval bridge with seven arches spans the river, with foundations tracing back to Roman times, and once served as part of an ancient royal road.

The islands serve as a gathering place where locals celebrate seasonal events and connect with nature through outdoor meals and festivities. This role as a community meeting space reflects how the area remains important for maintaining social bonds and traditions.

The site is easily accessible on foot and well suited for family day trips, as the connected islands are straightforward to explore. Ample shaded areas and seating are available, particularly if you visit early on warm days.

The area features two monuments honoring writer Xosé Neira Vilas and Adolfo Villa Donato, who dedicated himself to preserving this natural space. These tributes show how meaningful the islands are to the local community and how their story intertwines with the people who protected them.
