Tamar–Tavy Estuary

The Tamar-Tavy Estuary is a tidal waterway that stretches along the border between Cornwall and Devon, featuring mudflats, salt marshes, and freshwater wetlands across several kilometers. These different habitats support a wide range of plants and animals throughout the year.

The area gained protected status as a Site of Special Scientific Interest in 1991 due to the diversity of its habitats and wildlife populations. This designation safeguarded the estuary from harmful development and recognized its importance for conservation.

The estuary forms part of the UNESCO World Heritage Site of Cornwall and West Devon Mining Landscape, reflecting the industrial heritage of mineral extraction.

Walking trails along the water provide the main way to experience this area, with access points available at several locations near villages. The ground can be muddy and wet, especially at high tide, so waterproof clothing and sturdy shoes are recommended.

During winter months, rare wading birds such as avocets and black-tailed godwits gather here in significant numbers during their migration periods. These seasonal arrivals make the site a remarkable location for birdwatchers and nature observers.
