If you’ve ever wandered along a Cornish beach and spotted a glimmering piece of sea glass underfoot, you’ll know the quiet thrill it brings. I’m endlessly inspired by these naturally polished ocean gems. Whether you’re a local or visiting Cornwall, finding sea glass on Cornwall’s beaches is a magical way to connect with the coast — and maybe even begin your own jewellery journey…
Why Cornwall is Perfect for Sea Glass Hunting
With over 400 miles of coastline, Cornwall is one of the UK’s best regions for sea glass collecting. Its rich maritime history and powerful Atlantic tides mean the shores are scattered with softened shards of glass, shaped over decades — even centuries. From soft greens and aquas to rare blues and ambers, each piece of Cornish sea glass is a tiny piece of coastal history.
Best Beaches in Cornwall for Sea Glass
Looking to go sea glass hunting in Cornwall? Here are some of the top spots where collectors often find stunning pieces:
- Seaton Beach (near Looe) – A mix of sand and shingle, ideal for spotting weathered glass at low tide.
- Perranporth Beach – Vast and wild, this beach often reveals sea glass near the cliffs and rock pools.
- Marazion Beach (by St Michael’s Mount) – A scenic spot where colourful sea glass often appears after high tide.
- Portreath Beach – Rugged and dramatic, with a good chance of finding richly hued sea glass.
Tip: Search just after high tide or during spring tides when more of the shoreline is exposed.
How to Find Sea Glass in Cornwall
Finding sea glass in Cornwall can be a peaceful, rewarding activity — especially if you follow a few simple tips:
- Search at low tide – More of the beach is uncovered, giving better access to hidden treasures.
- Look near the tide line – Sea glass often collects where the waves drop it.
- Be patient and slow – Sea glass can be small and well-camouflaged. Let your eyes adjust and scan the sand carefully.
- Bring a small container – Protect your finds from chipping on the way home.
The Beauty and Meaning of Sea Glass
What makes Cornish sea glass so special? Each piece began its life as broken glass, discarded long ago. Over time, the ocean tumbles it into something smooth, frosted, and beautiful. It’s a natural transformation — one that reflects the very spirit of the Cornish coast.
