Seven people were rescued from Worm's Head on Thursday when they became stranded after being cut off by the tide.
Those rescued, a group of Swansea University students, were picked by the volunteer crew from the local RNLI lifeboat after they became stranded and unable to return to the mainland.
The group was taken back to shore in the lifeboat where they were handed over to the coastguard. It is understood they knew the causeway leading from the mainland to Worm's Head is only open for two and a half hours either side of low tide but had miscalculated the tide times.
The Horton and Port Eynon lifeboat, crewed by volunteers Will Metcalfe, Anthony Payne and Stuart Payne, launched at 4pm after the alarm had been raised by Coastwatch.
Harrowing RNLI video shows what it's like to drown:
An RNLI spokesman said: "If you are cut off by the tide do not attempt to wade to safety. It is extremely dangerous to attempt to do so.
"These students did the right thing and telephoned the coastguard. The RNLI would remind people when walking at or near the coast not only to check the weather conditions but also to check the tide times and to make sure that they plan walks to ensure that they are not cut off by the incoming tide."
The incident comes less than a month after a similar rescue made in August, when seven people were also rescued by an RNLI lifeboat crew after becoming stranded on Worm's Head.
