Antrim

The Antrim coast road runs about 25 miles between the cliffs and the sea, with nine glens coming down to it. The rock is basalt, the same flow that formed the Giant's Causeway. Scotland is 12 miles off at the narrowest point and visible on a clear day.

Donegal

Slieve League is about 600 metres from clifftop to sea, one of the highest sea cliffs in Europe. Errigal is the highest mountain in the county at 751 metres, and it's quartzite, so it turns pink in low light. Glenveagh National Park covers about 16,000 hectares behind them.
