Porth Diana and Porth Castell, Trearddur Bay, Anglesey
Porth Diana and Porth Castell are part of a series of smaller bays and coves that flank both sides of the main beach in Trearddur Bay. At only 2.02 hectares, Porth Diana is the smallest nature reserve on Anglesey, and committed to protecting our county flower, the beautiful Spotted Rock Rose! You’ll often find some welcome shelter in these pretty little coves.
Both bays are surrounded by rocks, made up of of mica-schist, and backed by a sea wall. Being far more protected than the main beach of Trearddur Bay, Porth Diana, especially, is used for mooring boats, especially those owned by members of the Trearddur Bay Sailing Club. Porth Castell, just to the south, is possibly the better bay for swimming. Both Porth Diana and Porth Castell, are great for family picnics. There’s ample opportunity for swimming, building sandcastles, climbing, exploring and rockpooling too!
With the surrounding coastline being so abundant in marine life and awash with wrecks and reefs, both bays are commonly used as a starting point for scuba divers. There’s even a dedicated dive shop just behind them.

There is disabled parking available and access to the beach is a 400m tarmac footpath which crosses the dunes and takes you to the beach. This makes access easy for those using a wheelchair or families with a pushchair.

The whole of this coast is popular with anglers. You’ll often see people fishing off the beach here, as well as from the rocks and ledges in the surrounding area. The cliffs at Ravenspoint are a great place to catch congers, codling, pollock, wrasse and dogfish - and all the usual suspects! Mackerel fishing, offshore, can be super here during the summer months.
