Standing in front of the crater from the volcano, Tangkuban Perahu, which erupted about 40 years ago.
After seeing Tangkuban Perahu, we hiked down about 3/4 of a mile to see another area that still has geological activity. It's no Yellowstone National Park or anything, but it did have one or two areas with bubbling water and tons of steam.
On the way back to the car.
That night we had dinner at the hotel -- the boys loved eating in the hotel room.
