Great pictures, @aiqabrago!
Brings me back to my trip to Sumatera a few years ago. I spend 9 days at Lake Toba and met many beautiful people, ate delicious food, rode the hill around the lake, visited the batak villages and the site of King Sidabutar. In short: I love Lake Toba! If I ever need some time to completely relax I will definitely go back again.
