Wallasea Ness

You anchor off here at the tip of Wallasea Island, where the River Crouch meets the open estuary — a genuinely wild and remote spot with almost nothing around but sky, saltmarsh and birdlife. This is the edge of one of the UK's largest coastal wetland restoration projects, built using 3 million tonnes of earth excavated from the Crossrail tunnels, so the landscape itself is a kind of accidental marvel.
