On the edge of the Brecon Beacons, Upper Gilwern Hill is a site long known for its well-preserved and complete trilobites. The hill is made up of rocks from the Lower and Middle Ordovician, and the privately owned quarry is accessible to parties staying at the onsite Shepherd’s Hut self catering accommodation. The trilobite fossils here are plentiful and the chances of finding a good number is very high. Ordovician, Private Quarry, Rating: ♦♦♦♦♦
Abereiddy is the best and easiest place in the UK to find graptolites. It is also an outstanding place where you can see and photograph in situ graptolites, crammed into the sloping bedrocks. Although this site is a SSSI (so hammering the bedrock is strictly prohibited), there is no reason why you would want to disturb the bedrock. The foreshore is full of rocks that can be picked up without tools and contain better specimens than those in the bedrock. Ordovician, Cliffs and Foreshore, Rating: ♦♦♦♦♦
Southerndown is a Jurassic coastal location that closely resembles the classic Lias sites of Somerset. The early Blue Lias is mostly thickly bedded limestones, with thin shale bands. The limestones are full of bivalves, with occasional ammonites. They sometimes also yield reptile remains and fish. Jurassic, Cliffs and Foreshore, Rating: ♦♦♦♦
Tucked away in the fold of a valley near Llandrindod Wells, in Mid Wales, sits Little Wern holiday cottage. The cottage has its own small quarry, which is solely open to visitors staying there. And what’s more, it is stuffed full of trilobite remains. Ordovician, Private Quarry, Rating: ♦♦♦♦♦
Cwm Craig Ddu is a roadside section found to the east of Llangammarch Wells, along the B4519.

This site is a SSSI, so hammering the bedrock is strictly prohibited. Silurian, Roadside Cutting, Rating: ♦♦♦

This disused quarry is situated along the main A470 through the Brecon Beacons. The quarry also contains a waterfall, which keeps the faces clean. There is strictly a no hammering allowed, due to SSSI rules and because the site falls within the Brecon Beacons National Park. However, loose material can be collected from, especially at the base of the waterfall and from the stream running through the quarry. Devonian, Disused Quarry, Rating: ♦♦
Penarth is the most popular location in Wales for fossil collectors. This is down to both the site being very rich in fossils, together being a major built up area. This site can be over collected but you still should come home with some finds. Jurassic, Triassic, Cliffs and Foreshore, Rating: ♦♦♦♦
