My wife and I were taken here by our driver who recommended this company.
We had never done rafting before so we had no idea what we were in for, but the guide leader Sam and our boat guide Kris were awesome. You get full instructions on land before hitting the water then the fun begins.
The Ayung River trip is about 10km with a stop halfway for a nice cold Bintang or soft drink & water.
Total time is about 2 hours in the raft with a delicious lunch provided back at the start point.
Professional video and photos available to buy which are good quality.
Getting down to the raft and back in the end involves walking down/up a lot of stairs. Take your time and enjoy the experience.
An absolute must do when in Bali.
