Druidston Haven

Pretty view

Abundant graptolites can be found at Druidston Haven. The site, like much of the Pembrokeshire Coast is an SSSI which means that although loose pebbles and smaller rocks may be investigated and collected, large boulders and the cliffs must not be defaced.


♦ Parking for a few cars can be found in lay-bys next to the small road that passes Druidston Haven. From here it is a short walk to a path that leads to the beach. The path slopes downwards and is perhaps a hundred meters long.
♦ When the beach is reached, look around for blocks of shale. These can be found at the end of the path to the beach and in coves a hundred meters or so to the north and the south.

FIND FREQUENCY: ♦♦♦♦♦ – Once the right type of shale cobbles are located and split, graptolites should prove to be plentiful.
CHILDREN: ♦♦♦♦♦ – The beach is easily accessible and fairly hazard free.
ACCESS: ♦♦♦♦♦ – Parking can be found a short distance from the beach. Once on the beach, shale cobbles are immediately found. Other areas with the cobbles are within a few hundred meters. The tide at this location does not reach the cliffs until near to high tide.
TYPE: – The cliffs at this location are mainly composed of shale. This is packed with graptolites. The cliffs themselves must not be damaged but there are plenty of rolled shale blocks in-amongst the shingle that can be split in search of graptolites.


Graptolites are abundant within the shale blocks at this location. Diplograptids are most common.

Although many specimens are found, as you would expect, on the bedding planes of the shale, many also appear to dissect the bedding planes and are very hard reveal in any semblance of completeness. This can be quite frustrating. Presumably this hindrance is caused by the extensive deformation of the rock layers in this area.

There are carboniferous sandstone blocks to investigate as well as the shale. These contain poorly preserved plant fossils. Investigate any of the smaller blocks of shale that are found within the small bays at this location. Please don’t attack the cliffs or the larger blocks of rock. There are also large blocks of sandstone to be found to the north of the bay.

Graptolites appearing to cross the bedding planes


The rocks at Druidston Haven are composed of Ordovician mudstone shales from the Mydrim Shales Formation. These form part of the Drefach Group and are of Caradocian age (451-461 Mya).

Graptolites are common in the black shales, which demonstrate the effects of the Caledonian (400Mya) and Variscan (290Mya) mountain building periods. As a result, the rocks are folded, faulted and distorted. Many of the graptolite fossils found here suffer from the same fate and can be disappointingly broken.

The sandstone found at Druidston Haven is of Carboniferous age and comprises rocks of the Pennarth Sandstone Formation (a sub-unit of the newly named Warwickshire Group). These sandstone rocks are of Bolsovian (previously Westphalian C) to Asturian (previously Westphalian D) in age (307-310Mya). These rocks were formerly assigned to the Upper Coal Measures.

Various graptolites


Common sense will suffice at this location. Watch the tide to make sure that you are not cut off in one of the small coves and don’t stand too near to the cliff face.


Most fossils at Druidston Haven can be collected from the foreshore within the loose shale. Please do not hammer the cliff.


This site is an SSSI. This Special Site of Scientific Interest, means you can visit the site, but hammering the bedrock is not permitted.
