It marks a record year for Northern Ireland's water quality standards as the EU's benchmarks grow increasingly strict, and represents a 100% increase over three years.
Ballyronan on Lough Neagh retains its Blue Flag status, while and Ballycastle Marina achieved the accolade for the first time, as the News Letter reports.
Other stretches retaining their status are Downhill, Benone, Portstewart, Tyrella, Whiterock and Portrush's East and West Strands.
Newcomers to the Blue Flag list are Cranfield West, Murlough and Crawfordsburn Country Park in Co Down, and Castlerock in Co Derry.
Meanwhile, seven beaches across Northern Ireland attained Seaside Awards for their high standards.
Environment Minister Alex Attwood said: “Today’s increase in Blue Flag and Seaside Awards is great news for Northern Ireland’s beach users and seaside towns as they know they can expect the best when they see a Blue Flag or a Seaside Award symbol."
