Temple Ulun Danu at Lake Bratan
It is a beautiful sight when you see the misty tops of the volcano Gunung Catur towering over the lake. Even though you can't enter the temple, the complex is really worth the visit. The temples located in the water are particularly nice to see. It has been photographed many times as you can find them in every Bali travel book or on post cards.
A couple of hundred meters from the Ulun Danu Temple you can also find the Bali Handara Kosaido Country club which is famous among golf lovers. If you don't plan to play golf, there is not much to see here. You can stop here for some lunch if you don't mind paying more than usual.
