Lake Maninjau is a lake in the sub-district of Tanjung Raya, Agam Regency, West Sumatra province, Indonesia. The lake is located about 140 kilometers north of Padang City, the capital of West Sumatra, 36 kilometers from Bukittinggi.
Lake Maninjau is located at an altitude of approximately 460 meters above sea level. Lake Maninjau spans 100 square km with a maximum length of 16 km and a maximum width of 7 km, with an average depth of 105 meters.
Historically, this lake was formed as a result of the volcanic eruption of Mount Sitinjau which occurred approximately 52,000 years ago. The caldera that was formed so broad then developed into a lake. This is the same as what happened to Lake Toba in North Sumatra and Lake Batur in Bali.
Because Lake Maninjau is a caldera, it is surrounded by steep hills. So that the Dutch used to get around the steep climb in making roads, they made a winding road climbing from Maninjau to the top. These turns become legendary and are called Turn 44 (Kelok 44). Driving skills are required when crossing this route
The famous Kelok (turn) 44 starts from Maninjau for about 10 km to Ambun Pagi. The road conditions are quite extreme with a number of uphill turns (180 degree bends), as well as several long and steep inclines. Around turns 3-5, there is a collection of monkeys that are quite tame, so that it becomes a tourist attraction in itself.
When we get to the top, we can see the fantastic view of Lake Maninjau from the top of the hill. This lake, apart from Google Maps, can also be seen on a manual map.
