Site of Community Importance Ria de Aveiro

The Site of Community Importance Ria de Aveiro is a lagoon system with branching channels and small islands along the Portuguese coast. It formed after a major storm and today creates a complex network of shallow waterways and marshland.

The current form took shape in the 16th century when Atlantic storms blocked the old harbor entrance and created a new water system. Human activities like salt extraction shaped this area for centuries afterward.

Salt harvesting has been central to life here for generations, with workers passing down their techniques through families. The old salt ponds still shape the landscape and show how communities adapted to this flat waterland.

The best time to visit is during spring and fall when the weather is mild and bird watching is most rewarding. Most exploration happens by boat, so be prepared for uneven terrain when stepping onto shoreline areas.

The system is known for drawing thousands of migrating birds during cold months, traveling thousands of miles to overwinter here. This regular bird exchange shows the global importance of this seemingly local habitat.
