The Severn Estuary Big Beach Clean 2026
The Severn Estuary Big Beach Clean is back this September, and we’re calling on communities, volunteers, schools, and organisations to get involved! Running from the 18th to the 27th of September 2026, the event is part of a wider national effort, aligning with the Marine Conservation Society’s Great British Beach Clean. We’re also working alongside the Welsh Partnership of Marine Protected Areas to help safeguard the unique environments that make the Severn Estuary so special.
Whether you’re based along the coast, near a river, or inland, you can play a part in helping to spruce up the Severn. Join a public event or set up your own clean in your local area – every piece of litter removed helps protect wildlife, improve water quality, and enhance the natural environment in this incredible estuary. You can find the map of existing beach clean events, links to our social media, and helpful resources from the Marine Conservation Society further down this web page. Let’s make 2026 our most successful Big Beach Clean yet!

Angling Line Recycling Bins
