Tirta Gangga is one of the most famous water temples in Bali, located about 2 hours from Ubud in East Bali. The temple was a former royal palace and has beautiful gardens and large koi fish. For just a few cents, you can purchase fish food to feed the fish and get up close to them. They also sell bread, but I don't recommend feeding it to the fish as it is harmful to them.

This location tends to get crowded with people taking pictures, so it is best to arrive as soon as it opens at 8 am to avoid the crowds.
