Lisfannon Strand at Fahan, near Buncrana, which is popular with Derry beach lovers.
Children visiting beaches in Donegal are to be issued with plastic ID bands.
The initiative is being introduced in an attempt to prevent the repeat of chaos on Rossnowlagh beach last year when a child went missing amid fears he was in the water.
The child went missing as thousands of people in their cars caused gridlock on the beach when they all tried to leave at the same time as the tide came in.
The Sligo 118 rescue helicopter and lifeboat crews were scrambled to the beach in an attempt to find the child who later turned up safe and well.
With warmer weather predicted, Irish Coast Guard units have started distributing wristbands to children on beaches around the country, including those in Donegal popular with Derry families.
The wristbands, which are disposable, allow parents/guardians to write their phone number on it and place on a child’s hand.
If the child gets lost the phone number can be contacted and everyone reunited quickly, minimising the need for a large scale search and undue concern for parents.
The wristbands are free and made of Tyvek material which is durable and waterproof.
They are also being made available at lifeguard stations and public buildings such as libraries.
