Book excerpt: At one time, according to the Catskill Institute, there were more than a thousand hotels spread across the mountains of Greene, Ulster, Delaware, and Sullivan Counties. The Catskills were an exciting world full of pleasures to be enjoyed, with summer and winter activities characterized by entertainment, food, sports, card playing, and food again. Catskill Hotels, with a collection of some two hundred images, tells the story of this world, which began with America's first resort hotel, the Catskill Mountain House, continued with places such as the world-famous Grossinger's, and can still be found today at Kutsher's Country Club, the Mountain House at Lake Mohonk, and a few other hardy resorts.
