This is one of the best volcano craters to see in Costa Rica. There are about 120 volcanos in the country, but only a few have accessible, visible craters, and none are terribly active. Still, the environment is unique, the sulfur smell interesting, and the sense of a massive force of nature impressive. The crater is about 1000 feet deep, and 3000 feet in diameter.
Things to know. The drive from San Jose airport to the top is about 90 minutes. Lots of twists and turns and a slow go in spots. Wonderful scenery in places along the way. The altitude is 3200 meters which may give some shortness of breath or a light headed feeling. The entrance fee is $10 per person. We forgot we were in the tropics and that the altitude would affect the weather. At the top it was about 50-55 degrees F, with a pretty strong wind. You need warm clothes. There is a concession stand right there to get hot or cold drinks, and small snacks. Kids could easily walk beyond the fencing so they need to be watched.
The signage could be better and more informative which is why the rating is 4 and not 5.
The volcanic ash field leading to the crater and the crater itself are variably cloudy so how much you can see is a bit of luck. We went from pretty dense fog to 80% clear and back again a few times in the course of two hours.
I was with four people total and we all loved it. Worth the drive and a couple of hours.
