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 We will drive for approximately an hour thru the Guanacaste mountain range and majestic views of the Miravalles volcano. We will continue our trip with a visit to "Las Hornillas", a place situated at the foot of the volcano, where you will see geysers all over the project. Here we will horseback ride to the forest and hike thru it for about 40 minutes to observe several waterfalls and some animals and plants. To relax after the hike we will get covered by volcanic mud and enjoy the natural hot springs that emerges from the volcano getting a beauty treatment from Mother Nature. We finish our trip with a delicious lunch and then back to the hotel.
