The place where the River Anllóns meets the Atlantic Ocean is a very productive environment offering a wide variety of food available to the wildlife that inhabits it. It is called the Anllóns Estuary or the A Insua Cove. Protected as an SCI (Site of Community Importance) of the Costa da Morte belonging to the Nature 2000 Network and a SPA (Special Protection Area for Birds) of the northern Costa da Morte, it covers an area of 1,145 ha.
The Camiño da Ribeira hiking trail (PR-G 148) reaches this point after crossing the boardwalk – an earth and stone dyke known as the O Couto boardwalk – and the wetlands, home to plants as interesting as the small cordgrass (Spartina maritima), grasswort – also known as pickleweed and marsh samphire – (Salicor ramosissima), sea rushes (Juncus maritimus), reeds (Phragmites australis), and bulrushes (Scirpus maritimus), etc.
From the "Xuncal pequeno" (Small Red Bed) near Currás and O Couto the path continues on to the bird observatory you see directly ahead. At this point, the route also connects with the Pondalian Route.
