A hundred years ago, high on the summit of Mount Tamalpais, stood a grand lodge with a breathtaking view. For 33 years, elegantly dressed men and women came to visit on the gritty steam trains of a famous twisting railroad known affectionately as the Crookedest Railroad in the World. They could dine, dance, and spend the night, and in the morning coast down the mountain in a gravity car. The Mount Tamalpais Scenic Railway had 281 curves in 8 1/5 miles. It had a branch into Muir Woods. It was built by business-minded conservationists in seven months in 1896 and climbed from a depot on the dirt streets of Mill Valley through a redwood forest and on to the rocky summit one-half mile above San Francisco Bay.
