The Tabacon natural hot springs
Nothing special, just like the way it looked
Arenal volcano, active since 1969; the smoke running down the front is actually lava, but you can't see it during the day (nor easily photograph it at night)
Not quite sure what this raccoon-relatives are called, but they like to hang out around Lake Arenal and wait for dumb tourists to feed them
Probably the only paved road in the whole country without Rhode Island-sized potholes
