Nolton Haven is a hamlet halfway along the coast of St Bride's Bay in Pembrokeshire, Wales.

An on-road section of route 4 of the National Cycle Network also runs through Nolton Haven.

The local rocks which form a partly fault-bound outlier of the main coalfield which lies to the south, are assigned to the Pennant Sandstone Formation.

They largely comprise a faulted series of mudstones, siltstones and sandstones with thin and contorted coal seams known locally as 'veins'.

[2] The strata were folded during the Variscan Orogeny and frequently dip at 20 to 30 degrees whilst several faults outcrop in the cliffs on the north side of the bay.
