Costa Rica is a country with lush jungles, pristine rivers, lakes, and waterfalls, and stunning coastlines. It is also a land with tall, cloud capped mountains. One of the most well-known mountainous regions of Costa Rica is the Arenal region. The primary peak in this region is the Arenal Volcano (Elevation 5,358 feet) which, until 2010, was also Costa Rica’s most active volcano. While the volcano is currently dormant, and climbers are not allowed on the volcano, there is a fantastic climb directly next to it, which is the Cerro Chato hike.
