On the flight from Perth to Indonesia, we saw some great water features in Western Australia. There were many circular depressions filled with water, near the rivers. I had seen these on Google Earth before but didn't quite know what they were. I'm still not sure I know why they happen.
Water quality seems a major concern in Indonesia and you'll likely see signs like this, even in relatively posh resorts.
On our second day we went from Denpasar to Ubud to see a cremation ceremony for a member of the royal family. The driver was happily obliging although somewhat confused by my excited arm flapping and insistence to stop whenever we crossed over a bridge. Many of the rivers in the rural areas are in canyons and are pretty.
It's the dry season right now so the water is low.
