Seaton Beach (Cornwall)

Seaton, Cornwall · PL11 3JD

A quiet sand-and-pebble beach east of Looe where finders report lots of sea glass in rare colours plus sea pottery.

About Seaton Beach (Cornwall)

Seaton is a sand, shingle and pebble beach in south east Cornwall where the River Seaton meets the sea, with a sandy walk to Downderry at low tide. It is well known locally but quieter than nearby beaches. Not to be confused with Seaton in Devon, which has very little glass.

Sea glass at Seaton Beach (Cornwall)

A recent finder reported 'loads of glass': white, green, amber, seafoam, soft blue, cobalt, red and aqua, plus sea pottery. Go at low tide; the beach gets rockier heading east towards Downderry.

Visiting Seaton Beach (Cornwall)

Parking
Street parking plus an overflow car park a short walk away (Sea Glass Map finder report).
Safety
Check the tide times before you go and head out on a falling tide, so you're never cut off. Keep away from the bottom of cliffs, wear sturdy shoes on rocks, and only take sea glass and other man-made rubbish: pebbles, sand and shells should stay on the beach.
