Ish Martinez, author of a new book, “Las Villas of Plattekill and Ulster County”, will take you on a nostalgic journey back to a time when “Las Villas” were the most popular vacation resorts for Latinos in the Northeast. Described as the Spanish Alps, Las Villas was a lively enclave of Spanish, Puerto Rican, and other Hispanic summer resorts in Plattekill, New York, and the Catskill Mountains from 1920 to 1990.
