The Cajón del Maipo is a valley that penetrates the Andes Mountains, with several small towns, the main one being San José del Maipo, a small city full of history, which was founded in 1972 and is considered a National Heritage site. The Maipo River gives life to the region and many ecotourism activities take place on its banks. It also irrigates the Cabernet Sauvignon vineyards, typical of the region. We wind further and further into the Cajón, admiring beautiful landscapes and renewing ourselves with the pure mountain air. The Termas de Colina, with its thermal waters heated by the nearby San José Volcano, is an incredible place to relax in one of its 9 natural and open-air pools, tucked into the mountainside. The water temperature varies in each pool, from 25ºC to 60ºC.
