Lower Fal & Helford Intertidal Site of Special Scientific Interest Adventures

The Lower Fal & Helford Intertidal Site of Special Scientific Interest (SSSI) covers the estuarine coastlines along the lower reaches of the River Fal and the Helford River in Cornwall, England. This sheltered estuarine environment supports extensive intertidal mudflats, sandflats, saltmarshes, and rocky shores that provide critical habitats for a wide variety of marine invertebrates, migratory birds, and fish species. The area is particularly important for overwintering wildfowl such as shelduck, oystercatcher, redshank, and curlew, as well as breeding seabirds like terns and egrets. The intertidal mudflats are nutrient-rich, supporting abundant benthic fauna that sustains these bird populations. Beyond its ecological significance, the site offers scenic coastal walks and birdwatching opportunities, attracting wildlife enthusiasts and researchers. The surrounding landscape features small fishing villages and historic harbors, giving visitors a glimpse into Cornwall’s maritime heritage. Access to tidal flats at low tide allows for exploration by foot or kayak, providing a unique perspective on a dynamic ecosystem where land meets sea. Low-impact recreational activities such as guided nature walks, photographic excursions, and tide pooling are popular while emphasising conservation. The area's protection under SSSI designation ensures ongoing preservation of these valuable habitats, helping maintain biodiversity and ecosystem function along this stretch of the Cornish coast.
