Ramsey Island lies half a mile west from the St David's Peninsula in Pembrokeshire, the most westerly point of Wales.

The island is dominated by the rocky peaks of Carnllundain and Carnsgubor, whilst the two small islands, Ynys Cantwr and Ynys Bery lie to the south.

It is known for its bird population including: gulls; pelicans; gannets; cormorants; albatrosses; petrels; etc.

Owned and managed by the Royal Society for the Protection of Birds (RSPB) the island provides a home for nesting chough, peregrine falcons and several species of seabirds.

Its vegetation includes important stretches of heathland and maritime grassland which are among the few truly unmodified semi-natural habitats in Britain.

Little surprise that associated with these habitats are many species of plant and invertebrate that are national rarities.

The breeding colony of grey sears is the largest in south west Britain, with up to 300 seal pups being born each year at the back of the cave systems and on the small beaches around the shore.

It is an island rich in legend dating back to the establishment of early Christian cells or chapels, first in AD 186 by Devanus or St Tyfanog as he was also known, and later by St Justinian.

The existence of Bronze Age cairns and probable iron Age field systems dates the influence of farming back some 5000 years.
