The Denes Beach at Southwold is a quiet shingle beach backed by sand dunes and marshes less busy than the main Southwold Beach. The beach runs northwards from the mouth of the river Blyth to the seaside town of Southwold.

It is popular with dog walkers or those wanting a rural beach. If you are visiting Southwold in the summer then this is the beach within walking distance that has no dog restrictions.

The beach has toilets, parking, summer lifeguards, and more facilities just a short walk away from Southwold.
