Giant's Causeway

It's sort of cool to see a geological landmark get visited by hundreds of thousands of tourists. But then you realize maybe it's not so unusual, when you remember how many people visit Yellowstone, Mount Fuji, Niagara Falls, the Great Barrier Reef, or even Iceland!

The Giant's Causeway is sort of what eastern Washington would look like if the Columbia River were an ocean. Ancient lava flows, cooled into giant hexagonal columns, stretching out into the sea. Covered with busloads of tourists who will also be stopping at Carrick-a-Rede, Bushmill's Distillery, and several filming locations for Game of Thrones before the day is out.

Apparently, the giant Finn MacCool (really! that was his name!) built the causeway to make it easier for him to vanquish his counterpart giant in Scotland, just across the way.
