East Lindsey has retained its Blue Flag status for central beaches in Skegness, Mablethorpe and Sutton on Sea.
A privately owned beach at Ingoldmells has also been awarded Blue Flag status.
Visitors to award-winning beaches can be sure of a clean, safe beach with great facilities and water quality.
"Blue Flag and Seaside Awards set the standard for our beaches, including the war against the litter and plastic that does so much damage to our marine environment. It's fantastic to see that Ingoldmells has also achieved Blue Flag status, meaning that nearly all the beaches in our District have been given the Award".
