From south Bali (Denpasar, Kuta, Nusa Dua or Sanur), head north towards Singaraja. There are small towns along the way such as Ubung, Sempidi, Mengwi (famous for its Pura Taman Ayun), Pacung, Baturuti and Bedugul (famous for its Pura Ulun Danu on Lake Bratan). This route is slowly climbing to some 1,000 meter above sea level with spectacular view of Mt Agung in the northeast could be sporadically seen. In the village on Pancasari, instead of going north to Singaraja, take a left and head west through the village of Wanagiri and Munduk. Along this route one could enjoy the bird's eye view of Lake Tamblingan.
Actually there are two main lakes (danau) in this area. I passed through the cliffs above Lake Buyan between Pancasari and Wanagiri. On the western end of Lake Buyan only I could start to see Lake Tamblingan.
Reputed to be the sister lake of Buyan, Lake Tamblingan is the smallest lake in the island of Bali. Enjoying the lake by its shores may take half-day trip through the virgin forest. Nonetheless, the view from the village of Munduk is sufficient enough to be inspired by its tranquility.
During my morning journey, the mist was still covering the lake surface, giving it an air of shrouded mystery. From Wanagiri to Munduk, there are a number of narrow rest stops where one could get a decent view of the lake.
If one is heading to Labuhan Lalang through this route, a quick pit stop doesn't cost much. The view is simply outstanding.
