Tukad Cepung Waterfall was a hidden gem a long time ago but is now one of the most famous waterfalls near Ubud. During 9 - 11 AM the light shines into the cave giving you these beautiful sun rays for photos. Unfortunately, this spot can get very packed with tourists but it is still 100% worth the visit. There is a small entrance and parking fee but the way itself is very beautiful. Make sure to stop at the cafe just before coming back up from your visit. They have fresh cold coconuts and amazing food.
