San Gil's showpiece is the mystical Parque El Gallineral, a 4-hectare park set on a triangle-shaped island between two arms of the Quebrada Curití and Río Fonce. Nearly all of the 1876 trees are covered with long silvery tendrils of moss called barbas de viejo (old man's beard), hanging from branches to form translucent curtains of foliage and filtered sunlight. It's like a scene set in JRR Tolkien's Middle Earth.
Several paths and covered bridges snake through the urban forest and over the rapids. After your hike, relax with a swim in the pool or sip a cerveza (beer) at one of the pricey restaurants and cafes.
