Following a spine of snow-covered volcanic peaks, this 583-sq-km national park provides access to some of the most stunning stretches of the Colombian Andes. Its varied altitude range encompasses everything from humid cloud forests and páramo to glaciers on the highest peaks. The main peaks, from north to south, are El Ruiz (5325m), El Cisne (4750m), Santa Isabel (4965m), El Quindío (4750m) and El Tolima (5215m).
