On the coast, about 3 miles S. of Caernarvon, Dinas Dinlle has a fine stretch of beach. The little village used to be the site of a great Roman Camp, the last vestiges of which can be seen on the top of a nearby hill. The hill has been a place of great interest for archeaologists, as Roman Coins and artefacts have been found there. A WWII machine gun posts still stands on the hill.
One of the most attractive points about Dinas Dinlle is the view south towards the Lleyn Peninsula, the three distinctive peaks of "Yr Eifl" are imposing.
