Here are just a few:
Pablo is standing in from of the Arenal Volcano. It erupts just a little bit almost every day. We saw the red glow of the lava after dark, but it stayed high up on the mountain.
The National Museum in downtown San Jose has many interesting exhibits. Mrs. H's favorite was the butterfly garden. Here is Pablo next to a zebra striped butterfly.
It rained most of the days we were in Costa Rica It usually was sunny in the morning and rained in the afternoon. When the raindrops started falling the paraguas, the umbrellas, showed up everywhere.
Here are Pequeno Pablo, Mrs. H, and her family being tourists at the Puntarenas beach.
Here is another link to lots of information (and some photos) about Costa Rica.
