The Bratan Caldera is located in the northwest of Bali and is a stunningly beautiful area with lakes, waterfall, and a botanical garden. The Temple at Lake Bratan (Pura Ulun Danu Bratan) is probably Bali’s most photographed temple on the island after Tanah Lot.
Mt. Catur is the summit you want to climb up to (we’ve been told it’s the one with the most breathtaking view). Unlike Mt. Batur and Mt. Agung, this volcano is extinct so you won’t be able to eat lava-rock cooked eggs at the summit. For hiking is roughly three hours up with many picturesque landscapes during the journey as well as various shrines and remains of sites where the Dutch used to flock for their weekend retreats. At the top you will be met with a beautiful view of Lake Bratan and its surroundings as well as a temple called Pura Puncak Manggu.
While the toughness of the hike no way compares to Mt. Agung, if your fitness is below-average you might want do some endurance training before attempting this climb.
