Paved Trail to Crater
  • It is one of the most accessible volcanos in the world! Only about an hour outside of San Jose, this park will please everyone. With a paved road to the park and a wheelchair accessible, paved trail to the crater, you will have no trouble looking down to the second widest crater in the world (9/10 of a mile wide).

  • Poas is one of the five active volcanoes in Costa Rica. You might just be around when its main, active crater shoots water up like a geyser in one if its frequent phreatic eruptions. The last big, recorded eruption was in 1996. Read more about the Volcano...

  • Interesting flora can be found here due to the high altitude and acid rains generated by the volcano. One in particular is called the poor man's umbrella. Their huge leaves are over 3 feet in diameter and really are big enough to be used as an umbrella.

  • The main crater is green due to its acid content. It is one of the largest volcanic lagoons in the world with a depth of almost 1000 feet and with a ph of near zero-- it is probably the world's second most acidic natural lake.

  • Only one of the 3 craters at Poas is active, one of the others has transformed into a cold-water lake, Laguna Botas, which flows down the mountain Interesting Flower feeding the Sarapiqui River. This crater has not erupted in 7500 years.

  • There are exciting day tours combined with coffee plantations, La Paz Waterfall & Gardens and rafting trips that you can join. Contact us for a great tour.

How do I Get There?

Contact us to organize a guided tour of the Volcano or for bird watching specialty tours.


You can take a taxi from San Jose or Alajuela. It will cost about $55 dollars from San Jose. 

Public Transit:

The public bus (TUASA) leaves daily from San Jose  (Avenida 2, Calles 12/14) at 8:30 am. It stops in Alajuela at the main bus terminal on the way. The journey lasts about 2 hours each way (from San Jose). You can return via bus, but there is only one departing Poas for San Jose at 2:30 pm.

Poorman's Umbrella


From Ajajuela, there are numerous brown signs with a picture of a volcano navigating you all the way through Alajuela and to the Volcano. 


  1. Best time to visit is early morning before the clouds roll in. However, even if it's cloudy, you might get lucky and the clouds will dissipate enough for you to get a glimpse of the crater.
  2. High Mountain TreesTry to visit during the dry season (December through April). Crater visibility is most consistent.
  3. It's chilly up there, bring a light jacket / sweater even if it looks like a sunny day. The weather can literally change in minutes.
  4. Weekdays are less crowded.
