I liked that the heavy cloud bank lifted for about 10 to 15 minutes so that I could see the crater. What I disliked was the sulfur fumes and the hike up hill. It would have been a severe bummer if I paid the park entrance, hiked up to the rim, only to be in a thick cloud of sulfurous gas.

It mat not look like your average volcanoe, but it is just as amazing. What makes it even better is that about a mile walk away, there is a Beautiful teal water lagoon sorrounded by a forest of trees. These to sites are spectacular and worth taking the trip to see.

I liked how you could get close and look down into the crater. Good photo opp. Botos lagoon is worth the 30 minute walk. Excellent and worth the trip. Be sure to stop and enjoy the local food on the way down

The view was great, the weather while we were there was perfect. A couple people in the group had a hard time breathing on the hike up due to the elevation and amount of particles in the air.

i'm costa rican, but i went to poas four years ago, and it was a little cloudy. however, it was REALLY awesome! i went with my family, and we got to go on the forest trail. it was a little humid, but it was worth it. I TOTALLY RECOMMEND IT!

hi i luved it so much i went there thirty times after and ate popcorn at the top were everyone dies i was the first person not to die there in 46 years wow!

Poas is not like any other volcano I had ever heard about or seen. It is a sulpher volcano. I didn't even know they had those before this trip. Poas is a beautiful volcano. The water in the middle is an incredible shade of blue and the land around it is desolate. I could even see the part of the volcano that was discolored by the sulpher. ...

I really like Poas. Arenal is certainly better, but you can't beat it as a day trip from San Jose. I especially think that families with young children will like it because it is fairly well marked and protected.
