Costa Rica in a few images

Waterfall:
If you look closely to the bottom-right you can see someone standing near the falls to get an idea of how huge this thing was.

Volcano:
This is an active volcano, during the day you can see rocks tumble down the side, at night you can see them glow and breakup falling down the side of the volcano.

Monkeys:
The rain forests are pretty amazing!

Pacific Ocean:
The Pacific Ocean made for great bogie boarding, the waves were so big that they really beat you up. If you fell off your board, you had a few seconds of being disoriented as to which way is up or down in the water.
