Castle Beach, Tenby

Tenby, Pembrokeshire · SA70 7BJ

Rocky-edged beach below Tenby's castle headland and harbour, where harbour glass and patterned sea pottery turn up at low tide.

About Castle Beach, Tenby

Castle Beach sits between Tenby's harbour and St Catherine's Island, below the castle headland. Tenby isn't a high-volume glass beach, but the rocky and pebbly margins at the foot of the cliffs and the drying harbour foreshore give genuine finds, including old sea pottery.

Sea glass at Castle Beach, Tenby

Green, brown and white are usual, with blue, aqua, amber and turquoise occasionally, rare cobalt, black, lavender and red, plus glazed and patterned Victorian pottery shards. A visitor to South Beach found only a piece or two, so focus on Castle Beach's rocky margins and the harbour wall at low tide.

Visiting Castle Beach, Tenby

Parking
Tenby multi-storey (Upper Park Road, SA70 7LT), Five Arches (SA70 7HZ) or the seafront car park (SA70 7EA).
Toilets
Public toilets at Castle Beach.
Safety
Check the tide times before you go and head out on a falling tide, so you're never cut off. Keep away from the bottom of cliffs, wear sturdy shoes on rocks, and only take sea glass and other man-made rubbish: pebbles, sand and shells should stay on the beach.
