Just a few miles south of Merthyr Mawr is this stunning promontory overlooking the Bristol Channel. Twin lighthouses stand guard against the elements; one is still operational, but the other is open for tours. This is also a popular picnic spot, and a small snack kiosk is open during summer months. Nothing beats this place at sunset, when the evening sky ignites in a riot of color. It's one of the most romantic spots in South Wales. There's no guardrail on the cliff, so keep a close eye on children.
