It's really really far from downtown so if you are planning to visit try to stay in Ubud and then visit. We took motorbikes and it was long drive. There is no entrance fee. Try to bargain about swings and nests. After all it's really nice view and must visit in Bali. And most important thing is that famous Bali Swing is way more too expensive and crowded. This place is not crowded and you can save a lot of money and make same pictures, maybe even better than there.
