About Dunas de São Jacinto Natural Reserve

Dunas de São Jacinto Natural Reserve
 

Dunas de São Jacinto Natural Reserve lies along the Atlantic coast of central Portugal near the town of São Jacinto, within the municipality of Aveiro. It protects one of the last extensive dune systems in the country, featuring shifting sand dunes, coastal wetlands, and a mosaic of habitats including maritime pine forests and salt marshes. The reserve plays a critical ecological role as a buffer zone between the ocean and inland areas, supporting diverse flora adapted to sandy, saline soils and providing refuge to an important variety of bird species, including migratory and resident birds such as plovers, sandpipers, and raptors. The region's mild Atlantic climate contributes to a stable environment with mild winters and warm summers. Historically, the area has been shaped by natural coastal processes, with limited human disturbance since its establishment as a protected area. Visitors come to Dunas de São Jacinto for birdwatching, peaceful walks along designated trails, photography, and observing the interplay of dune dynamics and wildlife. The reserve's pathways allow close access to dune landscapes without disturbing fragile ecosystems. Key landmarks include the São Jacinto lighthouse and viewpoints offering panoramic seascapes and marsh views. The reserve also forms part of the larger Ria de Aveiro lagoon system, enhancing its ecological significance. Its quiet setting appeals to those seeking low-impact outdoor experiences immersed in nature.
