A search was launched last Thursday after four young people went missing.
The alarm was raised when the youngsters on holiday from Ireland failed to meet up with their parents at Tenby's South Beach at the pre-arranged time of 4 pm.
Lifeguards on duty at the beach initially helped look for the 15-year-old girl, her two brothers, aged 12 and seven and a friend, also aged 15.
No trace could be found of the group, and approximately 6.15 pm the assistance of the local coastguard rescue team and the police was requested.
The Dyfed Powys police helicopter was also tasked to help in the search.
The quartet were eventually tracked down to the caravan they were staying in at Kiln Park via one of the girl's mobile 'phones and were then duly reunited with their distraught parents.
