Originally it was a small collection of farms to the north of the river Artro, close to where it enters the sea.

The village has a railway station, Llandanwg Halt, where trains on the Cambrian Line stop on request.

A new evening train service was introduced in 2015, which angered local residents when it was found that it would not stop at Llandanwg and some other halts.

[4] Morlyn guesthouse which used to be the village shop offers both bed and breakfast and self-catering accommodation overlooking the estuary and the Llanbedr space centre.

The parish church of Saint Tanwg is situated just behind the beach in the sand dunes just 20 metres (66 ft) above the high tide mark.
