The rewards in August will include Autumn Ladies Tresses (Spiranthes spiralis), Autumn Gentian (Gentianella amarella).

On the cliffs, Wild Cabbage (Brassica oleracea) and Sea Kale (Crambe maritima) on the beach.

The geology is also fascinating, with the Carboniferous limestone overlying Ordovician shales, faulted against Precambrian schists to the west. Expect some interesting fossils too.

There is car parking for only 5 cars so please lift share where possible to avoid too many cars. Additional parking is in Llanddona, 1.25 km along the road near the school (Ysgol Hên).

Assemble at the start of the walk (shown on the map in red) at 10:00am. If there is no room for parking we will ferry people to and from Llanddona.

The descent to the quarry is straightforward via a steep gravelly path with a steep climb back up. Some of the ground is uneven and there is a risk of trips and falls.

The route is considered fairly arduous and a reasonable level of fitness its required and is about 2 miles (3.25 km).

Stout boots and refreshments including water is recommended.

Limited places - maximum 16 people. Please book via Eventbrite: AGS meeting Tan Dinas Quarry
