The rock headland of Dinas at Porth Iago is a popular mark for anglers on the west coast of the Lleyn peninsula. Porth Iago is a south west facing cove beach very popular with families in the summer months, which can itself produce the occasional bass and coalfish. Access to the beach and indeed the rocks for fishing is by permission of the farmer at Ty Mawr and is restricted to the hours of daylight only. Pollack, wrasse, bull huss, and mackerel are all caught off Dinas.
