Gaylet Pot is the remnant of a former cavern, carved by the sea aeons ago. The sandstone coastal cliffs hereabouts are perforated by numerous caves, many of them penetrating deep inland. Gaylet Pot was originally a 100 metre long cave, within which the sea exploited faults to create a huge roofed cavern.
At some point, the roof collapsed, creating the huge open-air chamber that exists today. This cave, which is inaccessible except by boat, opens from the coastal cliffs as an archway over 20 metres high and 13 metres wide, tapering to just four metres high by three wide where it enters the Pot.
To view the Pot, head due west from Lud Castle for about 100 metres, and walk round to its inland side. The other three sides of the Pot are completely vertical, and deny good views. But from the west, grassy slopes allow you to look over the rim of the inner chamber, and see the shingle beach and entrance arch far below. At high tide, the sea can be seen washing up the beach.
