My favorite walk, possibly in the world, is along the coast at Wilder State Park in Santa Cruz, California. I live in Santa Cruz for the first three months of the new year, and always make the most of the natural beauty of the area. There are lots of stacks, like this one, and arches as well along the eroded coastline. I don’t know their names, but I call this one the Smokestack Stack because from this angle it looks like the smokestack of an old ship.
