The best way to explore the wild beauty of the park is by hiking the steep 9-mile (15-kilometer) trek up the Cerro Chirripó Grande, which is a challenging climb for even experienced trekkers. Two permanent shelters are along the way. Though the pass can be difficult, with elevation reaching nearly 10,000 feet (3,000 meters), the views from the top—including the Pacific Ocean and Caribbean Sea—are worth the effort. Less-fit travelers or those looking for a more laid-back experience have many scenic low-elevation options. On the other hand, if you want to turn up the adventure, take a whitewater rafting tour and navigate the roaring dips and bends of more than 20 Class III rapids along the Chirripó river.
