We start with the main course. In Poás, the time is very important those who climb after mid-morning usually find the crater covered by clouds. That is why we are going straight, when there is more chance of seeing it clear and before the mass groups arrive who make other stops earlier. We will visit Poás Volcano National Park, home to one of the largest and most accessible active craters in the world. From the main viewpoint you will walk to the crater to observe, when conditions permit, its volcanic lagoon and the landscape formed by its geological activity. You will understand the eruptive history of the Poas, its scientific importance and how it has shaped the soils and ecosystems of the region. There is also time for the surrounding mountains and the Botos lagoon, with its turquoise colour. The climate changes fast in this high mountain area: so get ready to experience one of the most emblematic volcanoes of Costa Rica according to the conditions of the day.
