Your Guide to Poás Volcano, Costa Rica  

Few volcanoes let you walk up to an active crater without a hiking boot in sight. Poás does.  

At 2,708 meters above sea level, a short paved path brings you face to face with one of the largest active craters on Earth. This is your complete travel guide to Poás Volcano, Costa Rica. 

Where is Poás Volcano in Costa Rica? 

Location and Geographic Setting 

Poás Volcano sits in the Alajuela Province, within the Cordillera Central. It is the centrepiece of Poás Volcano National Park in Costa Rica’s Central Valley. 

• From San José, approximately 1.5 hours by road 

• From Juan Santamaría International Airport, approximately 1 hour 

• No 4×4 required. Fully paved roads all the way to the park entrance 

Why Travelers Visit Poás Volcano 

• A main active crater approximately 1.5 km wide and 320 meters deep, one of the largest of its kind in the world 

• Laguna Caliente, a hyper-acidic crater lake that shifts between milky turquoise and sulphurous yellow 

• Laguna Botos, a calm, cold lake inside a crater dormant for 7,000 years 

• A dense cloud forest ecosystem starting just steps from the crater rim 

• Accessibility that no comparable active volcano in Central America matches 

What Makes Poás Volcano Unique? 

One of the Most Accessible Active Volcanoes in the World 

Most active volcanoes demand a full day, serious gear, and significant effort. Poás asks for none of that. 

• Getting there: paved roads, no 4×4 required, roughly 1 hour from the airport. 

• Getting to the crater:  a flat 10-minute walk from the parking lot 

• What surrounds it: strawberry farms, coffee country, and cloud forest 

The Main Crater Experience 

The scale registers slowly when you arrive at the viewpoint. 

• Width: 1.5 km across, one of the largest active craters in the world 

• Depth: 320 meters, with an acidic lake at the floor that glows and shifts color 

• Activity: steam rises from fumaroles; geysers have reached 250 meters at peak pressure 

• Visit format: Rangers escort groups of up to 50 visitors for approximately 20 minutes at the platform 

The Surrounding Cloud Forest 

Step back from the crater rim, and the landscape completely changes. 

• Botos trail: 1.4 km, 40 to 60 minutes, leading from the crater path to Laguna Botos 

• What you find: moss-covered trees, giant Gunnera leaves, orchids, and hummingbirds 

• Wildlife: the endemic Poás squirrel lives only here; the resplendent quetzal has been spotted on the trail 

• Laguna Botos: a calm, cold lake inside a crater dormant for 7,000 years, ringed by untouched cloud forest
