Attractions / Activities

This beach’s dramatic English name is based not just on its semicircular shape resembling a wide, open mouth. Its hellish dimension comes from a savage, south-westerly aspect that offers precious little shelter to sailors.

The old fishing village of Porthdinllaen has a deep-rooted attachment to the sea. The sandy beach spreads itself along a perfect cove and natural harbour, with a Lifeboat Station at one end.

Porthmadog’s bustling harbour was even busier 150 years ago. Discover the reason at this museum, which tells the story of the port’s shipbuilding and slate exporting heyday.

This small, picturesque National Trust beach, backed by steep grassy cliffs, is on the Llŷn Heritage Coast. It’s famously known as ‘Whistling Sands’, a nickname based on the sound the granules make underfoot when you walk over its gleaming sand.

There are two beaches in Pwllheli, Glan y Don Beach and South Beach. Glan y Don Beach, which is south-facing, is one of the Llŷn Peninsula’s ‘best-kept secrets’, and can be found at the rear of the new marina’s workshops and compound.

A remarkable underground experience. Abandoned in 1903 but now reopened to visitors, Sygun tells the story of Victorian miners. Nowadays, it’s hard to believe that such gritty industrial heritage exists amongst so much natural beauty.
