As the cost of cars and air conditioning decreased, fewer people took the train to Castlewood to escape the city’s heat. In the 1950s, the clubs and hotels began to shut down. Mobsters even used the area as a hide-out when they needed to drop off the map. The seclusion of these bluffs attracted visitors, and during prohibition there was a robust drinking and gambling culture away from the eyes of the authorities.

Much of the development occurred over the limestone bluffs north of the Meramec and the railroad tracks.

The Missouri Pacific Railroad brought hot city dwellers to cool down in the river, and Castlewood Village kept them entertained with hotels, clubs, bathhouses and more. In the early 20th century, clubs and vacation homes were developed along the Meramec River.
