A magnificent view of Bali can be seen from upper area of Lake Tamblingan and Lake Buyan. As you stand in looking down you will see the shimmering lakes reflecting the sun light. The air is much cooler compared to Kuta or Nusa Dua, and much fresher too. As you gaze around, you will see many mandarin trees, hydranger, tomatoes farm, vegetables farm, strawberry farm, as well many trees. Birds singing in the air, and butterflies wandering on beautiful flowers.
Located somewhere in the middle of Bali island, the two adjacent lakes is about 50 kms from Denpasar, the capital city of Bali. To reach this area, you can go to a village called Munduk. Even during the journey to Munduk village, you can already beautiful views of the forests and these lakes. From Munduk village which located in the upper area of the lakes, then you can drive down into the lakes. The tourists, that I know, don't usually go down to the lake but only viewing the wonderful panorama and taking a few snaps before heading to Lovina ( a tourist area in North Bali). Munduk village lies in the route from Denpasar to Lovina.
Lake Buyan and Lake Tamblingan is located close to other marvelous tourists destinations such as The Ulundanu Temple, ( the temple by the lake), Gitgit waterfall, (a 42 meters height waterfall) and Lovina beach. You can visit those places as well before heading to this place.
Well, just to give you an idea, Lake Buyan is twice as big as Lake Tamblingan (3.9 km2 versus 1,9 km2). Lake Tamblingan, however, is 3 meters deeper than Lake Buyan (90 mtrs and 87 mtrs respectively).
What can you do in the lakes? Apart from enjoying the scenery, the area of the lakes is an ideal place for trekking, bird watching, and camping. There is a small dilapidated "trekking information service" office close to the main street in Munduk village. They will be happy to give you information about where is the best place to start trekking or bird watching. They can provide you a local guide, if you need it.
The facilities is quite okay, although still pretty basic. There is parking area, if you drive your own car, and there is a place where you can rent a boat to go fishing in the lakes. I have been fishing once here, but, maybe fishing is not one of my specialty. There are also guest houses scattered around the villages nearby. Or there are places by the lake where you can sit and sip Bali coffee or some Bintang beer.
