We did the Bali Secret Waterfall tour and had such a great time. We didn't realise it would just be me and my partner in a car which was so much better than on a bus etc. The waterfalls were beautiful and considering how busy Bali can be they were genuinely fairly quiet and not too touristy. You need to be fairly mobile to get in and out of them though (lots of steep steps), which is something to bear in mind. Angga was our driver/guide for the day and he made the whole day absolutely perfect. His driving was so good and super chilled. We were a bit slow getting back up from some of the waterfalls but again Angga was super relaxed and just encouraged us to take everything at our own pace and enjoy the day. He took us to a delicious warung for lunch and even let us Bluetooth our own phone/Spotify playlist to the car for the day. If you are going to do the tour I would definitely recommend asking for Angga as your driver
