Viñales is a town in western Cuba. Its main street is lined with colorful colonial-era wooden houses, including the Municipal Museum, which explores the region’s history. Orchids and palms fill the sprawling Casa de Caridad Botanical Gardens. Viñales serves as a gateway to the Sierra de los Organos mountains and the Viñales Valley. The valley's tall, steep-sided limestone hills, known as mogotes, draw rock climbers.
