Tirtagangga
Tirtagangga is a water garden located in Karangasem, Bali. The gardens were built in 1948 by the then Rajah of Karangasem upon a natural spring considered holy by Balinese. It consists of three main areas spread over an area of three acres, set amongst beautiful terraced rice paddies and jungle terrain. The large pools of water contain many fountains, 
and swimming is not only allowed, but encouraged.
There are many places to stay in the area, including the lovely Villa Djamrud right in the Tirtagangga complex, and the adjoining Villa Tirta Ayu, which comprise the former Rajah's living quarters. We stayed in the so-called "Marble Suite Villa" of Villa Djamrud, and it was an unforgettable experience.
Once there, the best thing you can do, apart from relaxing and strolling about the gardens periodically, 
is to go on long walks around the surrounding countyiside. Tirtagangga is also within striking distance (by vehicle) of Tenganan, the fabulous and ancient traditional Balinese village which has until relatively recent times been closed off to outsiders. Though much-visisted and somewhat "touristified" today, it is still well worth seeing.
From Someone who Knows...
An interesting website with lots of archival photographs of Tirtagangga has been put online by the grandson of Rajah Anak Agung Anglurah Ketut Karangasem, the last Rajah of Karangasem, who built the gardens at Tirtagangga in 1948. The website can be found at www.tirtagangga.nl. It shows in photographs the development of the site though time.
In short, Tirtagangga is the ideal spot for a tranquil away-from-it-all holiday, and is well located for exploring other fascintating places in this little-visited part of Bali.
Highly recommended!
