Amazing experience and must visit on Bali!
Me and my wife payed 250k ticket for single person, so total 500k and we get local guide to take us through waterfall region.
Guy was giving his best to take photos of us, help us with river crossing and rock paths. Whole tour took 4 hours for us, because we went with small baby, and took us longer time for photos. Otherwise you can do it for 3 hours to not rush.
They say on entrance it is 90min walk, but it is possible only if you don't stop.
I think you can go without paying ticket, but you go by yourself, and if you are younger I recommend you to do it that way, bring clothes to get wet, towel, 1 liter of water is enough and you take 4-5 hours to explore waterfalls, coffee place at viewpoint and bring some slippers which are not slippery to walk, because whole area is a littlebit slippery and you must be careful.
