Criccieth Castle overlooks Tremadog Bay on the Llŷn Peninsula in North Wales. It was built in the 13th century and remains in remarkably good condition. It's well worth looking inside, although there is a charge, and you can learn about its history from boards.

As you might expect, it's blessed with absolutely fantastic views.

Black Rock Sands Beach

Highlight • Natural Monument

This long beach gets vast when the tide goes out and looks completely different from low to high tide. The 'black rock' comes from the colour of its headland, while the beach itself is fine golden sand.

The sand dunes behind are a Site of Special Scientific Interest and there's plenty of life to spot in the rock pools too. If you follow the beach around to the east, you'll reach Porthmadog.
