Poas Volcano
Poas Volcano: of 2,708 meters (8,885 feet), this volcano is one of the most impressive sites in Costa Rica. It has long been one of the country’s largest and most active volcanoes. At almost a mile in diameter (1.6 km), the crater’s rain-fed sulfuric pool still bubbles and emits smoke into the air, reminding you of its imposing activity. Although the last major eruption was in 1910, visitors can still see how the geysers explode in the air up to 250 m (820 ft) in height. Chances of getting wet are pretty remote as the crater descends almost 1,000 ft (300 m) and is one of the largest active volcanoes in the world. Standing on the rim, visitors often smell the sulfur in the air, which at times has proven to be acidic enough for the park to close. Around the huge main-crater is the beautifully blue-green colored Botos Lake (Laguna Botos) and on the opposite side, the von Frantzius cone.
