Dieng Plateau
Perched at 2,000 meters (6,562 feet) above sea level, Dieng Plateau is one of the coolest destinations in Indonesia, and not just weather-wise. Both a natural and cultural destination, there are many things to see and do in Dieng Plateau. Other than the sweeping mountain view of jungles and distant villages, this highland has a multi-colored lake, hot spring, and ancient Hindu temples. Once a year, tourists flock to the spot for a much-anticipated festival that includes traditional rituals, performances, and jazz above the clouds.
Prambanan
Prambanan (aka Lara Jonggrang) is after the Borobudur the most famous attraction of Java. This masterpiece of Hindu culture is located just less than 12 miles northeast of the city of Yogyakarta on the boundary with Central-Java. Prambanan was built in 9th century and is the largest Hindu temple complex in the country.
Kawah Ijen
The Ijen plateau's most extraordinary sight is the magnificent turquoise sulphur lake of Kawah Ijen. A night hike to the crater in which the lake boils will introduce you to blue fire, spectacular scenery and a group of men with what must be one of the world's most unusual jobs. Pay entry fees at the PHKA post.
Ujung Kulon National Park
On the remote southwestern tip of Java, this Unesco World Heritage, listed national park has remained an outpost of prime rainforest and untouched wilderness, virgin beaches and healthy coral reefs. Relatively inaccessible, few people visit Indonesia’s first national park, but it is one of the most rewarding in all Java.
Mount Bromo volcano
A visit to the Mount Bromo volcano is seen by many as one of the absolute highlights of a Java trip. Bromo is unique because of its location in a vast sea of sand - Tengger Sand Sea - from 8 to 10 kilometers at an altitude of 2100 meters. The sunrise at Bromo is truly breathtaking and is regarded as an unforgettable experience.
House of Danar Hadi
Danar Hadi is one of the world's finest batik museums. The handpicked favourites from the owner's private collection (1078 pieces from a collection of 11,000) are magnificently displayed on wooden trellises throughout 11 rooms of this grand old colonial building. An obligatory guided tour, helpfully tailored to the visitor's time and interest, covers the highlights among the antique and royal pieces on display. A demonstration of the craft is included in the tour and there's a shop.
