Chang-ni

Abereiddy (Welsh: Abereddi) is a hamlet in the county of Pembrokeshire, in west Wales.

It has a small beach which was awarded the Blue flag rural beach award in 2005. A large car park adjoins the beach, where in the summer an ice cream van can usually be found. The beach also has public toilets which are open from Easter to October half-term. The Pembrokeshire Coast Path gives fine walking in both directions. The Common which runs inland behind the beach lies within the Manor of Llanrhian.

It is home to the now famous Blue Lagoon, where the "Red Bull Diving" championships have been held. The Blue Lagoon was created when the wall of an old slate mine was blasted to let the sea in. It is also popular for "coasteering" where people dive into the sea, swim and clamber along the cliffs.

Following the coast path north leads to Porthgain. Abereiddy to Porthgain is roughly a forty-minute walk.

The coastal path taken in the other direction to the south east goes around St Davids Head and on to Whitesands Bay.
