La Robleda Natural Protected Area (Spanish: Área natural protegida La Robleda, or simply La Robleda) is a 254-acre protected natural area and conservation easement in Cayey, Puerto Rico. La Robleda, meaning 'the oak grove', gets its name from the high concentration of pink manjack (Tabebuia heterophylla)[1] trees, locally known as roble blanco, in the area. The pink manjack trees in this nature reserve bloom for a few weeks every year, creating a natural scenic spectacle of pink and white colors in the Sierra de Cayey.[2][3]
