Poás Volcano Tour & Birdwatching — Day Trip from San José
Select participants and date
You step out of the van and the air changes—an immediate coolness that strips humidity from the city and carries a faint sulfur tang that seems to warn and welcome at once. At 2,708 meters the Poás crater cuts into the sky like an open wound; steam coils and low clouds move through the bowl, and a ring of dwarfed shrubs and moss-smothered trees lean against the wind. The guide, a local biologist, points to a flash of emerald: a hummingbird hovers like a jeweled punctuation in the gray morning.

Adventure Tips
Dress in layers
Temperatures at the crater are often 5–10°C cooler than the valley—bring a windproof jacket and mid-layers.
Bring binoculars
The guide provides optics but a personal pair makes bird identification and photography easier.
Prepare for altitude
At ~2,700 m you may feel short of breath; take it slow on boardwalks and hydrate before the hike.
Expect variable visibility
Crater viewpoints can close on short notice due to gas or cloud—plan flexible timing for photos.
