We flew here from Yogya! It's a lovely place, indeed - have been there twice now and can imagine going back. Probably one of the better towns for tourism in Indonesia, but for daily living I probably prefer Jakarta, Makassar, maybe Denpasar if there wasn't so much traffic.
We just hired a boat yesterday to cruise around the mangroves looking for proboscis monkeys - saw four groups, which was fantastic, but the trees were quite thick so not clear views. An hour boat ride cost 17usd which we split with another couple. Tomorrow we're going to try and see the new capital city that is being built in the middle of nowhere - afaik construction has halted since the recession hit here but a lot seems has been finished... another failed mega-project in the making I'm sure.
Hope you're enjoying your trip! What part of the world are you in at the moment?
