Hi Irwan, I can answer some of your queries. Ciater is the national park on top of the mountain. It is an active volcano and you can really smell the sulphur in the air. The cost is 35,000 for a vehicle. It is free for locals but 300,000 for foreigners (without Indonesian citizenship card). The top is nice, there are a lot of restricted areas which is a shame. At the top, on a clear day you get a great view and there are lots of photo opportunities. Also there are several stalls selling food, drinks and touristy gifts. As always, if you buy, always pay approximately 40% of original asking price. Go to Ciater during the day only, at night it all closes and you wont be able to see anything. There is no visible magma or lava. Sari Ater is a resort, about 5 - 10 km away from Ciater, which you pay about 50,000 to get in. That gets you into all of the public areas and a few public pools / waterfalls. There are a few semi private pools which you have to pay an extra 20,00 - 50,000 more for. I have been told that this place is open all night and is very nice at 02:00 with a cool beer in a warm pool but I have never done this! Hope this helps!

Hi keo This is not a private hot spring. Locals come here too. Come by the evening and its less crowded. The private hot springs i know are in japan. They are called onsen. It was an interesting experience as i was in Nagano and it was cold. But Japan have their own rules and etiquette too if u wanna go their hot springs. Sorry if i cldnt answer. But have a good trip nevertheless. Feel free to ask me anytime.
