Dinas Dinlle is a small community on the north coast of the Llyn Peninsula, in the county of Gwynedd, North Wales.
The village centre, or promenade, has a number of beach shops and cafés/restaurants (the Surfer, the Beachcomber), a general store/gift/souvenir shop (the Gift Shop), a public house and restaurant (Dingles Restaurant & Bar), and is located on the road to Caernarfon Air World.
Behind the village, in a tidal inlet, is the Foryd Bay Nature Reserve, which is home to an abundance of wildlife.
Caernarfon Airport offers pleasure flights around both the Llyn Peninsula and the mountains of North Wales.
Dinas Dinlle has a large sand and pebble beach, the pebbles alone being visible at high tide - the vast areas of sand becoming visible at low tide level.
The excellent water quality makes the beach popular for swimming, fishing, windsurfing, surfing, canoeing, sailing, jet skiing and power boating and it has become necessary to create zones in the water to protect bathers.
The popular beach offers fine views towards both the Llŷn Peninsula and Llanddwyn Island on the Isle of Anglesey.
Dinas Dinlle Hillfort:
The cliff above the beach is known as Boncan Dinas and is occupied by the Dinas Dinlle Iron Age Hillfort.
The fort has been eroded by the sea, such that only a double semi-circular rampart remains. Finds of Roman pottery indicate a reoccupation in the 2nd or 3rd centuries.
The hillfort is a roughly oval defended enclosure, set on the summit of a drumlin. The enclosure has suffered considerable coastal erosion on the west side and from the beach below, the original ground surface beneath the Iron Age ramparts along with other details are clearly visible in the eroded cross-section. Within the eastern part of the interior are traces of circular or rectangular structures or enclosures, one being a possible sepulchral mound or alternatively a Roman pharos or lighthouse.
