We move to Puncak Lawang Lawang, a name of a plateau in Agam District located 1.210 meters above sea level. From this place, we can view the blue Lake Maninjau. From here we can see the whole view of Lake Maninjau. In the colonial era, it was used as a resting place of the Dutch nobility. Nowadays often used for international class paragliding championship because it is one of the best spots in Southeast Asia. To achieve the Puncak Lawang, we will pass the 44-turns (Kelok 44).
Look at this breathtaking view of Lake Maninjau. Lake Maninjau has an area of approximately 16 km long and 7 km wide. The average depth is 105 m, with a maximum depth of 165 m. The natural outlet for excess water is the Antokan river, located on the west side of the lake. It is the only lake in Sumatra which has a natural outlet to the west coast. Most of the people who live around Lake Maninjau are ethnically Minangkabau. Villages on the shores of the lake include Maninjau and Bayur.
The Maninjau caldera was formed by a volcanic eruption estimated to have occurred around 52,000 years ago. Deposits from the eruption have been found in a radial distribution around Maninjau extending up to 50 km to the east, 75 km to the southeast, and west to the present coastline. The caldera has a length of 20 km and a width of 8 km.
