Minimal fitness required—short walking at high elevation; be prepared for stairs and brief uphill sections.
Ride into cold, sulfur-tinged air and stand on the rim of one of Costa Rica’s most dramatic active volcanoes. This efficient half-day tour from San José combines crater viewpoints with coffee-farm scenery and short high-elevation walks.
You step out of the van into a cold, thin air that stings the face and carries the faint, metallic tang of sulfur. At 2,708 meters the landscape shifts quickly: the road climbs through bands of cloud, passing coffee terraces and small strawberry plots, and then opens onto the broad rim of Poás. Steam and fumaroles rise from the main crater, a raw, restless bowl that seems to breathe.

Morning tours often escape the mid-day cloud layer—book the earliest pickup available for the best chance at unobstructed crater views.
Temperatures at the crater can be 10–15°C cooler than San José; bring a windproof shell and a warm mid-layer.
Rain and fumarolic steam can make gutters and boardwalks slippery—sturdy, closed-toe shoes with grip are recommended.
Volcanic activity or weather can alter plans; call the operator 24 hours in advance to confirm pickup time and park access.
Poás Volcano National Park was established in the early 1970s to protect the unique high-elevation ecosystems and the region’s dramatic volcanic features.
The park restricts access when necessary to limit human impact on fragile vegetation; visitors should stay on marked trails and avoid introducing foreign seeds or litter.
Closed-toe shoes with good traction protect on wet boardwalks and uneven trail sections.
Layering lets you adjust to chilled crater winds and sun when clouds lift.
Hydration is important at altitude—refill with bottled water provided or at stops.
