Cerro Chirripó is the highest mountain in Costa Rica, with an elevation of 3,820 metres (12,533 ft). It is located in the Chirripó National Park and is noted for its ecological wealth. The high peaks in this and La Amistad International Park host important areas of Talamancan montane forest and Costa Rican Páramo with high endemism and an extremely high biodiversity. The peaks of these mountains, because of their height, constitute sky islands for many species of plants and animals. Snow has never fallen on the peak in the past 100 years or so, according to the University of Costa Rica, but hail is reported sometimes.
The great height of Cerro Chirripó relative to its surroundings is also evidenced by its particularly high topographic prominence of 3,727 m (12,228 ft), which makes it the 37th most prominent peak in the world.
From the summit, it is possible on clear days to see all across the country from coast to coast, from the Pacific Ocean to the Caribbean Sea.
Forest fires have occurred in 1976, in the 1990s, and in 2012.
Climbing Chirripó is possible by obtaining a permit from the National Park office in San Gerardo de Rivas. From the trailhead, the summit can be reached via a 19.5-kilometre (12.1 mi) hike.
Chato Volcano, sometimes called "Cerro Chato" (Spanish for "Mount Chato"), is an inactive volcano in north-western Costa Rica north-west of San José, in the province of Alajuela, canton of San Carlos, and district of La Fortuna. It is southeast of the nearby Arenal Volcano
It is believed Chato first erupted 38,000 years ago during the Pleistocene period and last erupted about 3,500 years ago. One of the lava flows is now the route for La Fortuna Waterfall. The hill has two peaks, named Chatito and Espina. A crater about 500 metres (1,600 ft) wide is filled with a lagoon, Laguna Cerro Chato.
The Miravalles Volcano is an andesitic stratovolcano in Costa Rica. The caldera was formed during several major explosive eruptions that produced voluminous dacitic-rhyolitic pyroclastic flows between about 1.5 and 0.6 million years ago. The only reported historical eruptive activity was a small steam explosion on the SW flank in 1946. High heat flow remains, and Miravalles is the site of the largest developed geothermal field in Costa Rica.
The Miravalles Volcano reaches an elevation of 6,653 feet (2,023 m) and is the highest mountain in the Guanacaste Mountains. The heat from the volcano also helps power a geothermal energy plant at Las Hornillas, which is run by the Institute of Electricity
Grecia is the name of the third canton in the province of Alajuela in Costa Rica. The canton covers an area of 395.72 square kilometres (152.79 sq mi), and has a population of 69,703. The capital city of the canton is also called Grecia.
The canton lies among ridges and valleys on the southwestern slope of Poas Volcano. One area is completely separated from the remainder of the canton by the Cordillera Central (Central Mountain Range). Known as Río Cuarto, this area lies on the Caribbean Plain, and is intended to form its own canton at some unspecified future date.
The Río Poás and the Río Prendes establish a large portion of the eastern border of the elongated canton, with the Río Sarchí serving the same purpose on its western edge. The Río Grande is the southern border.
