The world's top twelve cliff divers will be in action in St Davids from today, with the start of the Red Bull Cliff Diving World Series.
It's the first time the event has been held in the UK.
Organisers say the Blue Lagoon in Abereiddy was chosen due to the height of its cliffs and depth of water, as well as its potential as a backdrop for TV footage and photography.
The event has been part-funded by the Welsh Government, which has provided 'up to £100,000'.
The Welsh leg will be the penultimate round in the World Series, which also visits France, Norway, Portugal, the Republic of Ireland, the USA and Oman.
