SECRET waterfall in Ubud BALI? 🇮🇩 (kind samaritans, hostel life)

Where does the water from waterfalls come from anyway? I finally visit waterfalls in bali after my 4th visit here lol. The first 2 were relatively easy to get to and felt more like a photo-op destination. The last one got me on all fours, as I maneuvered my way through the rocky canyon. Opt for the last one if you're up for an adventure with nature!
