When it comes to volcanoes, few places in the world allow you to peer directly into a massive active crater—and live to tell the tale. In Costa Rica, Volcán Poás offers exactly that. With its steaming fumaroles, bubbling acid lake, and surrounding cloud forest, Poás is one of the country’s most popular natural attractions.
At 2,708 meters (8,885 ft) above sea level, Poás is an accessible adventure that combines raw volcanic power with highland beauty. Unlike Arenal, which requires a multi-day trip, Poás can be visited in just a few hours—making it one of the best day trips from San José.
Where Is Volcán Poás?
Volcán Poás is located in Alajuela Province, just north of San José.
- From San José: About 1.5 hours by car.
- From Juan Santamaría International Airport (SJO): Just 1 hour by car.
- Nearby Towns: Alajuela, Grecia, Sarchí, and Vara Blanca.
This accessibility makes Poás one of the most visited volcanoes in Costa Rica.
