The photos below were taken in on April 7th 2008. We were trying to find a new angle to photograph the volcano so we drove around some of the roads between the Arenal Dam and a road that connects to the Castillo road nearby the national park.
We set up a tripod in a ditch off the side of the road, not ideal but at the moment we stopped the conditions were clear. After about 30 minutes or so the clouds rolled in and made it too difficult to get a clear shot. Unfortunatley the clouds hung around the summit the entire time we were shooting.
As you can see we also have a fair amount of long exposure noise indicated by the blue specs that form above and behind the volcano. It was an fun adventure even though we did not get any fantastic photos.
