This is one of a series of posts on our 2012 trip to Costa Rica. If you like, you can start with the first post.

Our tour
Today we joined our group tour for the first day of an extensive journey around Costa Rica. We were going to see samples of every part of the country, from the Central Valley to the Rain Forest to the Pacific, and several places in between.

Poás Valley
This morning started with a trip up to Poás Volcano. It’s a beautiful drive up to the park. It was almost the start of coffee season, and we saw lots and lots and lots of coffee plants with their little red berries. We also passed many houses; they were all heavily gated. You could do well in the wrought-iron-and-razor-wire business here.

CVH at main crater of Poás
We were very lucky when we got to the top; it is often, if not usually, socked in by clouds, but today’s view was truly spectacular. The lake behind CVH in the photo is about 300 meters deep and has a pH of less than 1.
The sulfurous stench of the fumes wafting up from the center of the earth was impressive. I’m breathing heavily in this video because the air is little thin for a flatlander like me. Notice how the acid environment stunts the trees and bushes in the foreground.
