Alto de Galleiro Loop

The Komoot data suggests this hike takes approximately 2 hours and 48 minutes of moving time. However, with stops to enjoy the panoramic views, explore highlights like the Alto de Galleiro summit, or observe the "infinite lagoon," plan for a total duration of 3 to 4 hours, depending on your pace and how often you pause.

The trail is predominantly dirt paths (about 98%), with a small asphalt section. You'll encounter rocky and sometimes 'bald mountain' landscapes. Expect steep climbs over stones and along firebreaks, especially when ascending to the peaks. There's also a challenging 60-meter segment near the village of Mouro where the path is not clearly defined.

This trail is rated as 'moderate' by Komoot, but sections are considered 'difficult' due to steep ascents, rocky terrain, and a lack of a clear path in one area. It requires good fitness and sure-footedness. While rewarding, it might be too challenging for beginners or young children. More experienced hikers will find it enjoyable.

The trail is located within the municipality of Ponteareas. While specific parking areas aren't detailed, it's common for trails in this region to have informal parking near the starting point, often close to villages like Mouro. It's advisable to check local maps or recent hiker reports for the most convenient and safe parking options.

You'll be treated to impressive panoramic vistas throughout the hike. Key viewpoints include the geodetic vertices of Alto de Galleiro and Alto de Salgueirón, offering breathtaking views of the San Simón estuary, Vigo, and the Cíes Islands. A unique feature is the intermittent pond, often called the "infinite lagoon," near the summit, which provides stunning reflections when full. You might also encounter the 'musical' granite formation, Pedra Catanga, and potentially wild horses.

Yes, sections of this route overlap with other established trails. Approximately 15% of the hike follows the Sendeiro das Greas, and about 6% coincides with the GR 58 Sendeiro das Greas.

The presence of wild horses in the region suggests that dogs are generally allowed. However, due to the challenging terrain and the presence of wildlife, it's highly recommended to keep dogs on a leash for their safety and to respect the natural environment and other hikers.

Spring and autumn are generally ideal for hiking in Galicia, offering milder temperatures and lush landscapes. Summer can be hot, and some sections are exposed. Winter hiking is possible, but be prepared for potentially wet, windy, and colder conditions, especially at higher elevations, and ensure you have appropriate gear for slippery or muddy paths.

Currently, there are no specific permits or entrance fees required to access the trails in the Serra do Galleiro, including the Alto de Galleiro — circular route. However, always practice Leave No Trace principles and respect local regulations regarding nature conservation.

For the most dramatic views, aim to hike on a clear day to fully appreciate the expansive panoramas of the Ría de Vigo and the Cíes Islands. If you visit after a period of rain, you might be lucky enough to see the 'infinite lagoon' near the summit full, creating a spectacular reflective surface. Also, keep an eye out for the Pedra Catanga, a unique granite formation with local legends.

Given the moderate to difficult rating and varied terrain, sturdy hiking boots with good ankle support are essential. Bring plenty of water, as sources on the trail are limited (e.g., a fountain in Mouro). Layers of clothing are advisable due to changing weather conditions, and sun protection (hat, sunscreen) is important for exposed sections. A map or GPS device is also recommended, especially for the less-defined sections.
