Get involvedNational Marine Week 2026 | 25 July - 9 August
Join us for National Marine Week and discover the incredible journeys happening beneath the waves around Cornwall.
From vast ocean migrations to tiny adventures across a rockpool, our seas are alive with movement. This year, we’re celebrating the incredible journeys of marine wildlife – from whales and sharks crossing oceans, to seabirds soaring thousands of miles, and the small but mighty creatures navigating Cornwall’s shores.
We’re inviting you to explore these habitats and uncover the stories of the animals that depend on them. From watching for dolphins and seabirds, getting hands-on with rockpooling and shoreline discovery, or finding out how you can protect our seas, get involved and celebrate our epic underwater world.
Whether you’re new to marine life or a seasoned wildlife watcher, there’s always something amazing to discover.

Incredible journeys
From Arctic terns soaring from pole to pole each year, to humpback whales passing through Cornish waters on their journey between Arctic feeding grounds and breeding grounds off Cape Verde, our seas are full of extraordinary journeys. Eels and salmon travel between rivers and the open ocean as part of their life cycle, while basking sharks and bluefin tuna roam vast distances across the Atlantic. Even small shoreline creatures play their part – limpets return to the exact same spot on the rocks after feeding, and spider crabs migrate in large numbers along our coast. Together, these remarkable movements reveal just how connected our marine world really is.
National Marine Week 2026 celebrates all of these stories – big and small – and the importance of protecting the routes they depend on.
