This is the first comprehensive historical retrospective on Las Villas of Plattekill and Ulster County ever written. Ulster County was first settled in 1652 and officially became a county in 1683. Its rural nature, scenic beauty, and the Catskill Mountains have made it a popular vacation destination since the 19th century. Described in numerous news articles as the Spanish Alps, Las Villas, as they were collectively known, was a lively enclave of Spanish, Puerto Rican, and other Hispanic summer resorts in Plattekill, New York, and the Catskill Mountains. Starting in the 1920s and for the next 60 years, the area became the most popular vacation destination for Latinos in the Northeast, with an emphasis on music, food, language, and customs.
