A day trip to Anglesey and a view of Puffin Island and the Trwyn Du Lighthouse seen from Penmon Point. The Puffins
from which the island gets its modern English name bred in considerable
numbers at one time, with up to 2,000 pairs recorded. The Rat was introduced accidentally to the island, probably in the late 19th
century, and reduced this population to a very few pairs. A program of
poisoning these rats started in 1998 appears to have eradicated them, and the Puffin population has shown an increase since that date.
