The village of Bedugul is located on the western shores of Lake Beratan, right at the foot of Mount Tapak. With a dry climate and temperatures cooler than most any other place in Bali, this area is well-suited for activities like trekking or Hiking. The presence of lovely scenery and several unique temples makes it all the more appealing.
“Puncak” means “summit” in Bahasa Indonesian. Puncak Mangu is the top of Mount Mangu which located along the rim of the caldera above the lake. On the top of this mountain is the Pura Puncak Mangu, one of the more important temples in Bali. Access to the summit requires about 2.5 hours of hard climbing through the rainforest. The trailhead begins near the man made cave Goa Jepang; this cave was made by the locals at the time of the Japanese occupation in WWII.
Despite of the hard time to climb the top the reward is worthy; you can see a great view of Mt. Batur, Mt Abang — often accompanied by the locals (monkeys). The Mangu Temple is small, built by the first King of Mengwi and consists of a Padmasana, two Meru, and some nice bas-relief.
