Discover Poás Volcano: Costa Rica’s Majestic Crater in the Clouds

As your guide today, I’m thrilled to take you on a journey through one of the most awe-inspiring natural landmarks in Costa Rica: Poás Volcano (Volcán Poás).

Standing at 2,708 meters (8,885 feet), Poás Volcano is not just tall—it’s one of the most accessible active volcanoes in the world. Whether you’re here for the dramatic crater views, the cloud forest trails, or to witness the power of geothermal activity, Poás promises an unforgettable encounter with Costa Rica's raw, natural beauty.

🌋 What Makes Poás Volcano Unique?

As a tour guide, I’ve taken travelers to many volcanoes, but few are as dramatic and visitor-friendly as Poás. Here’s why:

✅ Gigantic Crater: One of the largest active craters in the world at over 1.5 km (0.9 miles) wide and 300 meters deep.

✅ Acidic Crater Lake: The Laguna Caliente is one of the most acidic lakes on Earth, often seen steaming or bubbling.

✅ Multiple Ecosystems: You’ll hike through cloud forests, dwarf vegetation, and volcanic landscapes in a single visit.

✅ Active Eruption History: Poás has a volatile past, with eruptions as recent as 2017—making it both fascinating and carefully monitored.
