Gembleng waterfall is a lovely hidden gem in Sidemen, just a one-hour drive from Ubud. The best part is the rock pool over the cliff where you can sit in with a stunning view of the area. If you Google the name of the waterfall you will be able to find the exact location. There is no official entrance fee but they ask you to leave a donation and write down your name before you enter. I usually recommend $2-3 minimum for donations. There are a few stairs to get up to the top of the waterfall where the rock pool is located, the waterfall itself is 30 meters.

This waterfall isn't as popular as others in Bali, for a more secluded experience, arrive before 10 am in the morning.
